Answer:
45 balloons.
Step-by-step explanation:
The complete question is:
Colin ties 5 groups of balloons to the fence. There are 3 orange balloons, 2 blue balloons, and 4 green balloons in each group. How many balloons does Colin use?
We know that in each group we have:
- 3 orange.
- 2 blue.
- 4 green.
So, we have 9 balloons per group and 5 groups. We have to multiply 9 by 5 groups, we have 45 balloons in total.
Therefore, there are 45 balloons in total.
