Explanation:

Question 38

Step1: Multiply numerator and denominator by 4 to get denominator 100

$\frac{7}{25}=\frac{7\times4}{25\times4}=\frac{28}{100}$

Step2: Convert fraction to decimal

$\frac{28}{100} = 0.28$

Step1: Recognize denominator is 10

A fraction with denominator 10 can be written as a decimal with one decimal place.

Step2: Convert fraction to decimal

$\frac{3}{10}=0.3$

Step1: First convert fraction to decimal (as in Question 38)

$\frac{7}{25}=0.28$

Step2: Multiply decimal by 100 to get percent

$0.28\times100 = 28$

Answer:

0.28
