Metric system?????\n\nWe BARELY know the system we're using now!!! Anyone who knows their Multiplication Table is considered a Mathematical GENIUS!!!

Why doesn't your mother already know that you are not very good at mathematics.\nMerely turning up for the lessons does not automatically mean you will pass. It is time for you to make an effort to understand and learn the work. You may need help with this.

they will never understand sister .... God bless you !!!

Pay attention in class little girl and you will understand more of your math problems... Still wish ya the best, GOD bless!

yes, she's a dumb***, but I'd still take a look at the pics.  Maybe they could do a sisters spread.

Wow.  Not one of these answers gives you a *general* way to approach this kind of problem (which is really what you asked for ... not just the answer, and not "that's easy" ... shortcuts are great, but you're asking for a *general* help with this kind of problem).  \n\nI've tutored kids and *adults* who panic when they see these problems, and so here are my tips to help.\n\nAll  word problems involve a basic 3-step process:\n\n1. Translate the words into math symbols.\n2. Do the math (play with the symbols using rules).\n3. Translate the math symbols back into words.\n\nIf you panic when you see word problems, it's probably because you're trying to do  Step 1 and 2 at the same time.  Stop ... translate the problem into symbols ... and *then* start doing the math.  \n\nWhy is this so important?  Because Step 1 requires some creativity ... where you're doing the hard part that varies from question to question ... that's where there are all sorts of bizarre distractions in the wording (maybe it's "Po" and "Jezebel" next time, maybe one's a lifeguard and the other a hairdresser ... this is where the question can throw all sorts of irrelevant crap at you ... you need to get rid of everything that is irrelevant (like the names of the girls).\n\nSecond, the actual math step (Step 2) involves repetition ... rewriting the same statements in different ways ... so if it's long words, this gets tedious.  So Step 1 is writing the sentences down using as few symbols as possible.\n\nStep 2 requires almost no creativity at all.  That's just applying rules to symbols ... like "subtract 4 from both sides" or "divide both sides by 2", that kind of thing.\n\nAnd Step 3 is simple, IF you remember what your symbols mean.\n\nIn this case:\n1. Translate the words into symbols:\n"The sum of Cora's age and Rose' age is 40."\nC + R = 40\n"Cora is 4 years older than Rose."\nC = R + 4\n\n2. Manipulate the symbols.\nC + R = 40  ... and\nC = R + 4\nso (rule: rewrite first eq. using definition of C from the second eq.)\n(R + 4) + R = 40\nso (rule: we can reorder things added together)\nR + R + 4 = 40\nso (rule: subtract 4 from both sides)\nR + R = 36\nso (rule: replace additions with equivalent multiplication)\nR * 2 = 36\nso (rule: divide both sides by 2)\nR = 18\nso (rule: substitute back into original equation 2)\nC = R + 4 = 18 + 4 = 22\n\n3. Translate the symbols back into words:\nR = 18 ... "Rose is 18 years old."\nC = 22 ... "Cora is 22 years old."\n\nI hope that helps.  Feel free to email if questions.

I am so so so good in Math!! I'm like the smartest one in my class!! But I can't help you cuz I don't knnow who you are!! And I don't know any information about this contest!!

I would try to find songs for remembering the facts. Also, many people do not consider practicing the "count bys" or skip counting to remember rather than the actual math problems. Try having her sing one of the songs for a few days. Then ask her the facts. If she forgets when you are practicing facts, remind her of the song. Here is one example, but you would really benefit by borrowing a video or CD with all of the count by facts. Here it goes. \n\nThe itsy bitsy spider learns to count by 8s - 8, 16, 24, 32, and 40, 48, and 56, 64 and 72, 8 x 10 is 80, that's the end.\n\nI teach third grade and learned this technique from my special ed. collaborative math teacher who's special ed. kids learned multiplication facts through this strategy. This way they have another way to associate and connect the facts rather than just by the facts.\nGood luck!

Give her a break. Everyone is here coz they didn't really listen in class or need help. That's why we are here to answer them.\n\n1) 11% (275/2500 x 100 = Answer)\n\n2) 963 (900/100 x 107 = Answer)\n\n3) 750 s (300/40 x 100 = Answer)\n\n4) 7550 (8882/100 x 85 = Answer)\n\n5) $20442.50 (18500/10 x 110.5 = Answer)\n\n6) $5875.20 (6400/100 x 8.2 = Answer) \n\nI've done it for u, u better buck up in ur maths. These are the basics.

Go back to math class and figure it out!

Looks like someone is trying to get there math homework done.  Tsk tsk.  Square roots are easy - there is a button to do them on the calculator you should probably blow the dust off of.\n\nDid I say that?  Thanks for my 2 points and have fun cheating your way though high school math!\n\nAnd since it doesn't look like you're listening to your teacher, here's a math web site to get you started on the road to learning!

15 + 7x = 10x \n\nIt will take her 5 seconds\n\n15 + 7(5)= 10(5)\n50 = 50

I'm sorry, but how could you not know this?\nThis is basic elementary math and if you don't know how to round you are in trouble.\nIt's 0.1 by the way

Lots of people have trouble with this, so don't feel bad about it.  Let's see if this helps:\n\nSuppose you have to find the LCD of 1/2, 1/5, and 1/8.    What you have to find is the smallest number that you can divide 2, 5, and 8 into.  So let's look at them and see what happens.\n\n2 x 5 = 10, so 10 is the first number we check.  Can you divide all three numbers into 10 evenly?  No, you can't divide 8 into 10, so 10 won't work.  \n\nNow try 2 x 8 = 16, so we check 16.  Can you divide all three numbers into 16?  NO, you can't divide 5 into 16.\n\nNow try 5 x 8 = 40, so we check 40.  Can you divive all three numbers into 40 evenly?  Yes, so most likely 40 is the LCD.  To double check, think about waht other numb ers divide into 40 evenly, for example 2 x 20 = 40.  Is it possible that 20 could be the LCD?  No,  becasue you can't divide 8 into 20 evenly.\n\nSometimes the only nuimber that will work is what you get when you multiply all three numbers together, that is, 2 x 5 x 8 which equals 80, but in this case there is a number smaller than 80 that works.\n\nSo we would have 1/2 = 20/40, 1/5 = 8/40, and 1/8 = 5/40.  I don't know if this makes it any clearer to you, but I hope it helps.  Stick with it.  And ask someone you know to explain it to  you in their way, and you will find a way that makes it stick for you.
