Dianna and Becky were playing on the same soccer team and took turns being goalie. They stoped 9 out of 10 shots made against them. If the other team scored 3 points, how many balls did Dianna and Becky stop from going into the net?

27 balls

Step-by-step explanation:

If Dianna and Becky stopped 9 out of 10 shots made against them.

It means they allowed in 1 out of 10 shots made against them.

This is best solved using ratios

Proportion of Shots Stopped : Proportion of Shots allowed=9:1

If the other team scores 3 points, it means the number of shots allowed =3

Let x be the number of shots stopped

Number of Shots Stopped : Number of Shots allowed=x:3

Therefore:

9:1=x:3

Cross multiplying

x=9 X 3 =27

Dianna and Becky stopped 27 balls from going into the net,

60: 45 =12: 9 =4: 3 so the answer is 4: 3
