marysya [2.9K]

<u>Answer:</u>

4

<u>Step-by-step explanation:</u>

We are given that a PE class has 12 boys and 8 girls. The teacher needs to divide in maximum number of teams so that each team has an equal number of boys and girls.

For this, we will factors of 12 and 8 and their greatest common factor.

12 = 4 × 3 = 2 × 2 × 3

8 = 4 × 2 = 2 × 2 × 2

The greatest common factor is 4, therefore the maximum number of teams with equal number of boys and girls is 4.

A car uses 1 liter of gas every 12 kilometers. How many meters can the car travel on 3 liters of gas?
astra-53 [7]
<u>  1 liter </u> = <u>12 km
</u>3 liters     x km
<u>
</u>x= 12km x 3 liters ÷ 1 liter
<u />x= 36 km

But since we want to know how many METERS the car can travel, convert km to m:

<u> 1 km   </u>= <u>1000m</u>
36 km     y m

y= 1000 x 36m ÷ 1 km
y= 36000m

Hope this helps!
