Question 762990
If x is increased by 12% it is multiplied by 1.12:x + .12x = 1.12x<P>
If y is decreased by 2%, it is multiplied by .98: y -.02y = .98y<P>
1.12x/.98y = 6/7<P>
You can multiply either side by 1 without changing its value.  Multiply the left side by 1 in the form of 100/100 to remove the decimals.<P>
112x/98y = 6/7<P>
Multiply both sides by 98/112.<P>
x/y = 6/7 * 98/112 = 6/7 * 7/8 = 6/8 = 3/4.
