Question

Audrey and Lauren began reading a novel on the same day. Audrey reads 15 pages a day and Lauren reads 5 pages a day. If Audrey is on page 75​, on what page is​ Lauren?

Answer 1

Lauren has read 25 pages. if you divide 75 by 15(the number of pages a day) you get 5, meaning 5 days have passed. Then you need to multiply laurens pages per day by 5. which is 25

Answer 2

If Audrey is on page 75, then Lauren would be on page 25.

What is ratio?

"It is the comparison of two quantities of the same kind"

What is proportion?

"It is an equation in which two ratios are equal."

For given question,

Audrey reads 15 pages a day and Lauren reads 5 pages a day.

So, the ratio of number of pages for Audrey and Lauren would be,

15 : 5

Let 'n' be the number of pages Lauren read when Audrey is on page 75.

So, the ratio of number of pages would be,

75 : n

Both the ratios are in proportion.

$\Rightarrow \frac{15}{5} = \frac{75}{n}\\\\\Rightarrow 15\times n=75\times 5\\\\ \Rightarrow n=25$

This means, Lauren is on page 25

Therefore, if Audrey is on page 75, then Lauren would be on page 25.
