im just making sure, but is \n37.5/100 already in simplest form? wut about 5.3/100? HELP?!\nif they're not, can u tell me the simplified answer?

No they are not. You can never have a decimial in the numerator. The answer for the first one is 3/8 and the second one is 53/1000. \nTo get the answer move the decimal in the numerator one place and in the denominator one place too to make it equal. Then simplify.

4x+y=37     ---------> (*-0.05)\n 0.25x+0.05y= 5.5\n\n  -0.2x-0.05y= -1.85\n 0.25x+0.05y= 5.5\n 0.05x=3.65\n        x= 73\n\nSo there are 73 QUARTERS AND -255 NICKLES IT MAY NOT SEEM LOGICAL BUT WHEN YOU PLUG IT IN IT WORKS\n\n4(73)+y= 37\n292+y=37\ny=37-292\ny= -255

you want to know why\n\n2/3% of 5,000= 33.3\nfirst take 2/3 and put into decimal form. which is .6667 then move decimal place over (2) spaces to convert to %.  That makes it .006667.\nNow multiply .006667 x 5,000 and the answer is 33.3350. or the 33.3 you have in the answer.

It is 1, just like 0.3333... *is* exactly 1/3 and 0.6666... *is* exactly 2/3 and 0.9999.... *is* exactly 3/3 = 1.\n\nIt's not *close* it just *is*, exactly equivalent.\n\nThere is no trick to it... ask any mathematician and they will confirm that 0.9999.... repeating is just another way of representing 1.0.\n\n1/9 = 0.1111...\n2/9 = 0.2222...\n3/9 = 0.3333... (1/3)\n4/9 = 0.4444...\n5/9 = 0.5555...\n6/9 = 0.6666... (2/3)\n7/9 = 0.7777...\n8/9 = 0.8888...\n9/9 = 0.9999... (1)\n\nor use this proof:\n\nx = 0.9999...\n10x = 9.9999...\n10x - x = 9.9999... - 0.9999...\n9x = 9\nx = 1\n\nTo say that 0.9999.... doesn't equal 1 because it might eventually end and be different than one is like saying 0.0 repeating might not equal zero.\n\nCheck Wikipedia or any of the math forums to see that 0.9999... is confirmed to be 1, despite what our intuitive logic might say otherwise.

4.4.........the zeros cancel themselves otherwise the answer would be 8 but because of decimal point locations, its just 4.4.....\n\n\nhow did u come up with the answer?

Yeah, it is the same as cubed root of 25, but here's how you can go about solving the question to get the answer in simplest form. Cubed root of 5 squared is the same as five squared to the one third (5^2)^1/3\n\n\nMultiplying 2 by 1/3 gives you an exponent of 2/3\nSo your final answer in simplest form is 5 to the 2/3\n\n\nP.S. 8.3 is wrong. Try cubed root of 25 on the calculator, and try five to the two third. They both give you 2.9, not 8.3

I'm not sure what front end rounding is?\n21.7 is close to 22\n3.98 is close to 4\n22-4 = 18\n53.9 is close to 54\n2.56 is close to 3\n11.8 is close to 12\n54+3+12 = 69

Take a=0.080808. I will assume that the last 08 digits are repeated. This process will work for decimal to fraction conversions\n\na=0.08080808 etc\n\nMultiply both sides by 100\n\n100a = 8.08080808 etc\n\nSubtract first from the second\n\n99a = 8\n\nTherefore a = 8/99 = 0.08080808 etc\n\nTry the other ones

31.25% = 0.3125 (decimal) = 5/16 (fraction in lowest terms)\n0.75% = 0.0075 = 3/400\n72% = 0.72 = 18/25\n465% = 4.65 = 4 13/20 or 93/20\n0.032% = 0.00032 = 1/3125\n\nHope this is what you were looking for.

The answer is:  4.47, and that's all there is to it!\n\nOk Vanessa, all you have to do is pull up your calculator (Start>Accessories).\nI am not suggesting you don't work it out in your head first: it's just basic. Check the answer on the calc, or, if you get stuck....go back.... to POWERS OF HIGH HOLY ROOTISM   SQUARE YOU KNOW, 1x1+(2x2)+2+(10-5)/1=       Simple:\n1+4+2+5/1=12

Well.. 5 x 2998730787 would give  you 14993653935 and then you divide that by 7888443 and it would give you 1900.7114502823941302485167225015... I would recommend that you round that to probably 1900.7115... I hope this helps and best of luck with math

$1.19 made up of \n4 pennies\n4 dimes \n1 quarter \n1 half dollar\n\ndarn that was a tough one i thought it was 94 at first then when i saw you said it wasnt i re thought it i came up with .99 almost immediately but then i saw you say it was between $1 and $1.50 so that got me thinking again. once i looked againat how i came up with the .99 getting the extra 20 cents was easy\n\ni'm not surprised i got it though I could join mensa i have a 145 I.Q.  it's good to know somone can still put me through my paces  \n\nthanx again for the mental gymnastics\n\ngot anything else???

You cannot get back to ten from 3.333  it will not work. That fraction will always be missing. it got lost in the division. Anyone who says  that 3.33333 times 3 equals 10 is mistaken. If that were so, then why doesnt the calculator show 10 when you myultiply?  No, math is not as perfect and everyone brags it out to be.

Ok to change a decimal into a percentage just move the decimal over 2 spaces. In example .58 is 58% and .03 is 3%. Now it has been a while since school for me but if a mixed number is 1 3/4 or something to that extent you take the bottom of the fraction multiply it by the whole number and add the top number of the fraction. So 1 3/4 is equal to 7/4. To make that a percentage divide the top number by the bottom number which makes it 175%. I could be way off for your mixed numbers, but it has been awhile. Hope I could help a little!!
