could you work out the problems so i could get a better understanding how to solve x

math  Ms. Sue, Thursday, May 5, 2011 at 1:28pm
x/100 + 6/100 + 75/100 =1
x/100 + 81/100 = 100/100
x/100 = 19/100
x = 19
Try the second one yourself. I'll be glad to check your answer.

what about this one

math  Ms. Sue, Thursday, May 5, 2011 at 1:41pm
You're on the right track and close. However, you missed 2/90 in the original problem.

3/191/19+7/19+x/19=1
x=193+1+7
x=16+8
x=24

In this problem, 19 is the denominator. When adding and subtracting fractions with the same denominator, only add or subtract the numerators.
