Answer: B. y=2/5 x
Step-by-step explanation:
Hi, to answer the question we have to analyze the information given:
- 2 out of every 5 balloons are red
- Number of balloons: x
- Number of red balloons: y
Since 2 out of every 5 balloons are red, the ratio for red balloons is equal to 2/5. if we multiply that ration by the number of balloons he uses (x), we will obtain the number of red balloons (y).
Mathematically speaking:
y=2/5 x
The correct option is B.
