Answer:

5/4

Step-by-step explanation:

Lets suppose a quantity A that has a value of x

A = x

25% of A is = x/4

now adding this 25% to get 25% increase in the original value

A' = x+ x/4

A' = 5x/4

A' = 5*A/4

This means that , in order to increase the value by 25% in a single step we must multiply the the original value by 5/4.
