Answer:
The answer is 4000 balloons.
Explanation:
Using the rule of three:
- 1 carton → 10 boxes
- 4 cartons → x boxes. // multiply 4 carton by 10 boxes and divide by 1 carton
If 1 carton is 10 boxes, then 4 cartons of ballons will be 40 boxes.
- 1 box → 10 packages
- 40 boxes → x packages. // multiply 40 boxes by 10 packages and divide by 1 box.
If 1 box is 10 packages, then 40 boxes will be 400 packages.
- 1 package → 10 balloons
- 400 packages → x balloons. // multiply 400 packages by 10 ballons and divide by 1 package.
If 1 package is 10 ballons, 400 packages will be 4000 balloons.
