Question

Delilah does 841 jumping jacks in 4 minutes. She does her jumping jacks at a constant rate. How many jumping jacks can Delilah do per minute?

Answer 1

841 jumping jacks per 4 minutes

`(841~jumping~jacks)/(4~minutes)`

Divide both sides by 4.

`(841)/(4) / (4)/(4) = (210.25)/(1)`

Delilah can do 210.25 (or 210) jumping jacks per minute.
