Question

Laila loves to read. She got a new book that has 840 pages. So far, she has read 315. What percent of the book has she completed?

Answer 1

Answer:

39.38% or 39.375%

Step-by-step explanation:

315/800 =

315 ÷ 800 =

0.39375 =

0.39375 × 100/100 =

0.39375 × 100% =

(0.39375 × 100)% =

39.375% ≈

39.38%

Answer 2

Answer: 37.5%

Step-by-step explanation:

First the fraction

Since the book in total has 840 pages this will be the denominator of our fraction.

The number of pages she read (315) will be our numerator.

This is so because she read only 315 out of the 840 pages.

Our fraction will therefore be- 315/840

In terms of percentage, what we do next is to multiply the fraction by 100.

So we end up with-

(315/840) × 100

This will give your answer 37.5%

Extra example (for clarity)-

John has 8 apples, he ate 4, What percent of the apples did he eat?

4 the number of apples he ate

8 the number of apples total

make your fraction

4/8

multiply by 100

(4/8) × 100 = 50%

hope this helps!
