Question 714434: if x is increased by 10% and y is decreased by 10%.what is the ratio of x to y? explain
Answer by KMST(5328) About Me  (Show Source):
You can put this solution on YOUR website!
10%=10%2F100=0.1

x increased by 10% would be
x%2B0.1x=1.1x

y decreased by 10% would be
y-0.1y=0.9y

The new ratio after those changes would be 11%2F9=1%262%2F9 of the old ratio:
1.1x%2F0.9y=%2811%2F9%29%28x%2Fy%29
