The double number line shows the amount of time a hen needs to lay 1 egg.
Scorpion4ik [409]

I realize the double number line in this exercise can be as shown in the attached image, in that case, the table, correctly completed is:

Eggs      Time (hours)

 3                   <u>75</u>

 <u>4</u>                  100

 12                <u>300</u>

Method to complete the table.

First, you must see the double number line (attached image), in this we identify a hen needs 25 hours to lay 1 egg, by this reason, to identify the time required for a certain number of eggs, just multiply the number of eggs by 25 (the number of hours shown on the double number line), then:

  • 3 * 25 = <u>75</u>
  • 12 * 25 = <u>300</u>

To calculate the number of eggs taking into account the time, you must divide the hours by 25:

  • 100 / 25 = <u>4</u>

In this way, <u><em>you can check that the answers are 75, 4, and 300 respectively, to complete the table in the correct form</em></u>.
