Allisa [31]
I believe B. is your answer. If you use the ac method, you will multiply 8 and 3 which is 24. So now, what factors of 24 will give you 10?6 and 4

By what percent will the fraction change if its numerator is increased by 25% and its denominator is increased by 20%? please an
d1i1m1o1n [39]
<h2>Answer:</h2><h2>The new fraction will chnage by 1.25 : 1.2 ratio, (i.e) = 1.04 %</h2>

Step-by-step explanation:

Let the fraction be represented as \frac{x}{y} 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  = \frac{x + 0.25 x}{y + 0.2 y}

= \frac{1.25 x}{1.2 y}

= (\frac{1.25}{1.2} ) \frac{x}{y}

The new fraction will chnage by 1.25 : 1.2 ratio, (i.e) = 1.04 %
