Below are the answers:
19/100 + 6/100 +75/100 =1
18/10- 2/10- 4/10 -2/10 = 1
explain it to me please because I'm confused
could you work out the problems so i could get a better understanding how to solve x
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.
x/90 -10/90-4/90-2/90=1
18/20-6/20+x/20=1
x=20-18+6
x=8
Your last problem is correct.
x/90-10/90-4/90-2/90=1
x/90-6/90-2/90
x/90-4/90=90/90
x=86
what about this one
You're on the right track and close. However, you missed -2/90 in the original problem.
3/19-1/19+7/19+x/19=1
x=19-3+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.

i subtract 6/90-2/90
thanks a lot
