3. reading alejandro read 4 pages in a book in 6
minutes. how long would you expect him to take to
read 6 pages at this rate?

Alejandro read 4 pages in 6 minutes, then it would take him 9 minutes to read 6 pages

Solution:

Given that Alejandro read 4 pages in a book in 6 minutes

Therefore,

4 pages = 6 minutes

Let us find the time taken to read 1 page

time taken to read 1 page = time taken to read 4 pages divided by 4

Thus to read 6 pages at this rate, multiply time taken to read 1 page by 6

Therefore it would take 9 minutes to read 6 pages

answer: 42

use a calculator to find that 845/73 = 11.575

the whole part of the answer is 11. multiply this by 73 to get 11*73 = 803.

subtract that result from 845 to get 845 - 803 = 42
