Carly and gina read the following problem in their math class:

seven cereal bars were shared equally by 3 children. how much did each child receive?

carly and gina solve the problem differently. carly gives each child 2 whole cereal bars and then divides the remaining cereal bar among the 3 children. gina divides all the cereal bars into thirds and shares the thirds equally among the 3 children.

a. illustrate both girls’ solutions.
b. explain why they are both right.

Part a) and Part b) see the explanation

Step-by-step explanation:

Part a)  Illustrate both girls’ solutions

Carly

Carly gives each child 2 whole cereal bars and then divides the remaining cereal bar among the 3 children

so

1) Each child receive first 2 whole cereal bars

the remaining is

2) Divides the remaining cereal bar among the 3 children

Each child receive 1/3 cereal bar

3) Each child receive in total

Gina

Gina divides all the cereal bars into thirds and shares the thirds equally among the 3 children.

so

1) Divide the total bars by 3

Each child receive

Part b) Explain why they are both right

Compare the results

Carly ---->

Gina ---->

Convert mixed number to decimal number

so

therefore

Carly and Gina are right
