Answer:
9/5
Explanation:
original fraction : x/y
new fraction = .9x/(.5y)
= 9x/5y
(9x/5y) / (x/y)
= 9x/5y * y/x
= 9/5
= 1.8
so it increased by 80%
e.g suppose we had 100/200 or 1/2
new fraction = 90/100 or 9/10
new ratio = (9/10) / (1/2)
= 9/5
Suppose that we have a fraction. Let use 10/10 for example. Let do the transformation and see what happens to the fraction.
10/10 ----> 9/3
The number changed from 1 (10/10) to 3 (9/3).
The fraction increases by 200%.
