Miranda is taking tennis lessons in one lesson, she returned 36 balls out of all the balls served to her. If she returned 40% of
the balls, how many balls were
served to her?
1 answer:
Answer:
90 balls
Step-by-step explanation:
Set up proportion
36/x = 40/100
Cross multiply: 40x=3600
Solve for x
x=90
To check work:
40 percent of 90 would be 36
90(0.4)=36
