To celebrate Children's Day, Teacher Zhang bought 48 balloons to decorate the classroom. The ratio of red balloons to pink balloons is 7: 5. How big is the red balloon?
Hello, I'm glad to answer your questions.
Solution:
Suppose there is X in The Red Balloon, then X: (48-x) = 7: 5.
Simplified to 5X=7(48-X).
5X=336-7X
12X=336
X=28
So, there are 28 red balloons, 48-28=20 pink balloons.
