Question

A printer is printing photos. For every 15 photos, the printer takes 3 minutes.

Complete the table below showing the number of photos and the time it takes to print them.

Answer 1

3:15, 5:25, 7:35, 8:40, 10:50

Explanation:

When I first tried this I thought it was for every one there was fifteen. I messed up then looked, realized, and changed it. For every 3 there is 15 so 15 ÷ 3 = 5 so when I saw the 5 I multiplied it by five to get 25 then continued throughout. Your first step when doing these problems again is to divide (but make sure you divide the right number) then once you find out that sweet number, multiply is by the time to get the photos, and divide by five on the photos to get the time.

Hope you got this right!

Answer 2

The table completed showing the number of photos and the time is

Photos 15 25 35 40 50

Time 3 5 7 8 10

Completing the table showing the number of photos and the time

From the question, we have the following parameters that can be used in our computation:

For every 15 photos, the printer takes 3 minutes.

So, we have

Rate = 15 photos/3 minutes

Evaluate

Rate = 5 photos/minute

Using the above as a guide, we have the following:

Missing 1 = 5 * 5 = 25

Missing 2 = 35/5 = 7

Missing 3 = 5 * 8 = 40

Missing 4 = 50/5 = 10

Hence, the missing values in the table are 25, 7, 40 and 10
