Question

What percentage of 150 m is 30 m ?​

Answer 1

20% of 150 m is 30 m

GIVEN:- 150 m and 30 m

TO FIND:- What percentage of 150 m is 30 m?

SOLUTION:-

• Percentage implies the fraction of 100
• Percentage of a = a/100
• of implies multiplication

According to the question,

Let the percentage be x

x of 150 = 30

$\frac{x}{100} \times 150 = 30 \\ \frac{150x}{100} = 30 \\ 1.5x = 30$

Dividing both sides by 1.5

$\frac{1.5x}{1.5} = \frac{30}{1.5} \\ x = 20$

Hence, 20% of 150 m is 30 m
