Question

Hank has read 25 percent of his book. If Hank has read 150 pages, which equation can be used to find the total number of pages in the book? StartFraction 25 times 6 Over 100 times 6 EndFraction = StartFraction 150 Over 600 EndFraction StartFraction 100 times 4 Over 25 times 4 EndFraction = StartFraction 400 Over 100 EndFraction StartFraction 25 divided by 1 Over 150 divided by 1 EndFraction = StartFraction 25 Over 150 EndFraction StartFraction 150 divided by 2 Over 100 divided by 2 EndFraction = StartFraction 75 Over 50 EndFraction

Answer 1

Answer:

x = 600 pages

Step-by-step explanation:

Let the total books pages be x

Given that

Hank had read = 25% of x

25% of x = 150

$\frac{25}{100} x = 150$

=> $\frac{1}{4} x = 150$

Multiplying both sides by 4

=> x = 150 * 4

=> x = 600 pages

Answer 2

Answer:

150=$\frac{1}{4}$ x, or 4(150)=x

Step-by-step explanation:

Let's use x to represent the total number of pages in the book.

If 150 is a quarter of the whole book, then 150 is equal to a quarter of x

150= .25(x)

We an go further and multiply both sides by 4 to cancel the .25

4(150)=x

We can finish solving and x=600 pages
