Answer 1

Answer:

Decrease bu 20%

Step-by-step explanation:

I go to RSM and if this is the RSM question: By what percent will a fraction decrease if its numerator is increased by 20% and its denominator is increased by 50%?; Here is the answer 20%.

Answer 2

Given:

The numerator of the fraction is increased by 20%

The denominator is increased by 50%

To find:

The percent increase/decrease in the fraction.

Solution:

Let us assume that the given fraction is 100/100 = 1

So, we will increase the numerator and denominator as given in the question

The increase in numerator = 120

The increase in denominator = 150

The new fraction will be = 120/150 = 12/15

We can see that this number is less than 1, therefore the fraction will decrease

The decrease in fraction = 1 - $\frac{12}{15}$ = $\frac{1}{5}$

Therefore the percent decrease = 0.2 x 100 = 20%

Therefore there will be a decrease in fraction, a decrease of 20%.
