Story pieces - in blue

Math problems - in red

BREAKING NEWS IT'S A AN ALIEN INVASION!!!!

THE LITTLE GREEN PEOPLE ARE FINALLY TAKING BACK WHAT THEY THINK IS THEIRS!!!
Unless......... I solve three proportion questions correctly they will destroy us all!!!
It's up to me to save you worthless people with my incredible brain power in math!!!!!

2.Your friend missed the lesson on proportions. Explain
how to use a proportion to solve this problem.
Cheryl is selling marbles. What is the cost of seven marbles?

The first question is answered correctly and the aliens are getting back into there spaceships.

3. a) Write a proportion based on the following scenario:
Three balls cost $1.25. What is the cost of 12 balls?
