Answer:
140 cm for 7 friends and 20 cm or 12 friends
Explanation:
We first have to change the 2.4 m to centimeters.
2.4 m x 100 = 240
then we do 240 ÷ 12 because they are 12 people they need to share it evenly with 12 people. to make it easier we do.. For getting cm of 7 people
(24x10) ÷ 12 = 20 x 7 = 140
(24÷12) x 10 =
2 x 10
20 cm per friend
140 cm for 7 friends
It was 20 because there are 20 cm for 12 friends
