It was a warm bad summer day in the year 2020 and the some of the most dangerous aliens were planning to invade the whole Earth by firing a SUPER laser at Earth unless we answer 3 proportional questions.

The questions are:

Delia was paid $35 for 5hours of babysitting. How much should she recieve for 3 hours? use a unit rate to find the answer.

Delia will recieve $21 in 3 hours.

David can saw alog into 3 pieces in 7 minutes. If he continous sawing at a constant

rate. how long would it take him to saw a similar log into 6 pieces?

A small gear turns 18 times in the same time a large gear turns 4 times. How many times will the large gear turn if the small gear turns 54 times? Draw a diagram to help set up a proportion

and solve the problem.

and solve the problem.
