Question

a fraction,when it reversed it increased by 125%.what is the original fraction?

Answer 1

Answer:

This fraction is 2/3.

Step-by-step explanation:

Let`s say that a fraction is n/m.

When it is reversed, it is increased by 125%:

m/n = 225/100 * n/m

m/n = 2.25 n / m

We can cross multiply:

2.25 n² = m²  / √

1.5 n = m

So when n = 2, m = 3

The fraction is 2/3, and when it is reversed, it becomes 3/2 ( increased by 125 % )
