Question

Carla has 5 times as many notebooks as her brother does they have 42 notebooks between them, how many note- books does Carla have?​

Answer 1

Let the number her brother has = x

She has 5 times as many so she has 5x

Together they have 42:

X + 5x = 42

Add x and 5x to get 6x:

6x =42

Divide both sides by 6:

X = 7

The brother has 7

Carla has 5*7 = 35

Answer: Carla has 35 notebooks
