Test Problem:
2)In a bag of red and blue candy, the ratio of red candy to blue candy is 3:4. If the bag contains 120 blue candy, how many red candy are there?
Step 1) Assign variables
Let x = red candy
Write the items in the ratio as a fraction.
red/blue= 3/4 = x/120
Step 2) solve equation by cross multiply
3 times 120; 4 times x
360= 4x
Step 3) get x by itself
x= 360/4
360 divided by 4 =90
answer 1) 600:1
2) 90
