Step-by-step explanation:
Let the fraction be represented as [tex]\frac{x}{y}[/tex] where x is the numerator and y is the denominator
Given that numerator will increase by 25 %, = 25% x
= 0.25 x
Given that denominator will increase by 20 %, = 20% y
= 0.2 y
The new fraction becomes = [tex]\frac{x + 0.25 x}{y + 0.2 y}[/tex]
= [tex]\frac{1.25 x}{1.2 y}[/tex]
= [tex](\frac{1.25}{1.2} ) \frac{x}{y}[/tex]
The new fraction will chnage by 1.25 : 1.2 ratio, (i.e) = 1.04 %
