By what percent will a fraction decrease if its numerator is decreased by 40% and its denominator is decreased by 25%?

This is experimental fraction question

We start with a high fraction and work downwards to a lower fraction

Reduce 10/16;  = 6/12 = 1/2   observation = the fraction gets smaller by 1/5

Reduce  10/12 = 6/9 = 1/3  observation = the fraction gets smaller by 1/4

Reduce 8/8 = 3/2 observation = the fraction gets smaller by 1/3

We notice that when the fraction is whole number it reduces by 1/3

When the fraction is 3/4 it reduces by 1/4

When the fraction is 5/8 or 10/16 it reduces the fraction by 1/5

When the fraction is already half

We can prove it reduces again by a smaller than 1/5 number

1/2 = 10/20 = reduction = 6/15 = it has reduced by 3/15 = 1/6 to 1/7

This is because the numerator is reduced 40% and the denominator is reduced by 25%  

Step-by-step explanation:

20%

Step-by-step explanation:

( 0.6 ÷ 0.75 ) * 100 = 0.8 * 100 = 80

100% - 80% = 20%
