Vonna scored 35 goals at soccer practice. Her ratio of goals to misses was 7:8 . How many times did she miss?

Answer 1

Set up the ratio as a fraction: 7/8. Then set the goals and misses as a similar fraction. Since you don't know the misses, use a variable, "m": 35/m.

Set the two fractions equal to each other : 7/8 = 35/m.

Cross multiply: 7m = 8 x 35.

7m = 280

Divide both sides by 7: m = 40. She missed 40 times.
