find the LCD of 5/6 and 3/5 that is 30 so, \n1.)25/30 - 18/30 = 7/30\n2.)48 and 66 can be divided by 6 so it becomes 8/11\n3.)divide seven by eight so you will get the result of 0.875 move two decimal places to the right so it becomes 87.5%\nI cannot answer the last two because i was confused by the signs you are using.well i hope that my first three answer helps.

first you figure out the number of possible outcomes you can have. which would be 6x6 = 36. \nThen you figure out how many combinations you can make to make it greater than 7:\n5 and 3\n5 and 4\n5 and 5\n4 and 4\n4 and 5\n3 and 5\nwhich is 6.\n6 over 36 is one sixth. therefore your answer is 1/6.

A percent is part of 100.  So 5% = 5/100 = .05.\nOnce you have the decimal just multiply the numbers.\n.05x14.00\n.15x25\n.28x600000

Forty.\nCross multiply/divide  \n5/8=25/x\nmultiply both sides by x and both sides by 8\nyou get\n5x=25 times 8\n\nx = (25x8)/5  or x=25/5 x 8 or x = 5 x 8

Well, first you want to isolate the "x".  So, divide out the left side-this gets you 3x/6 + 4/6 = 2/5.  Take 4/6 from each side, so x/2 = 2/5 - 4/6.  You have to make the fractions have the same denominator, so you get x/2 = 12/30-20/30, or x/2 = -8/30.  Now multiply each side by 2, so you get x = -16/30, or x = -8/15.\nplug it back in to check, so (-24/15 + 60/15)/6 is the same as (36/15)/6, which is the same as 6/15, which reduces to 2/5.  O Ho! We got it!  x DOES equal -8/15..  That was fun-I havent done that kind of math for a long time..

Convert the fractions to a common denominator which is 24\n2/3 = 16/24\n3/8 = 9/24\n5/12 = 10/24\n\nThen add them up. \n16 + 9 + 10 = 35 or 35/24 \n\n35/24 = 1-11/24

55/5 - 5 = 6\n\nClever, no?\n\n... The answer above only works in one equation if you add the parentheses (5x5 + 5)/5 = 6. Take them out and you have 5x5+5/5 = 25+1 = 26.

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.

I agree with homeschoolmom. To show her statement in equation form:\n\nRatio of 2 to 5 = 2/5\n\nNext, multiply the numerator as well as the denominator by 20 to get an equivalent fraction whose denominator is 100.\n\n(2/5)(20/20) = 40/100\n\n40/100 is the answer in fraction form.\nTo change it to percent, remove the fraction bar and the 100 and change with a percent symbol.\n\n40/100 = 40%  Answer.\n\nRemember, the denominator should be 100 so that it can be changed to a percent.

I think you're talking about "average," so you add up the numbers and divide by how many numbers you've added.\n\nthe average of 5, 6, and 7\nis 5+6+7 divided by 3\nso it's 18/3 = 6\n\nhope that helps, sorry if I'm way off
