Question

A pitcher threw 6 strikes out of every 10 pitches if she threw 35 total pitches how many were balls

Answer 1

21

Explanation:

Simplify the ratio 6 : 10

The simplified ratio is 3 : 5.

The ratio is 3:5 now we have to figure out what the ration of 35 is so lets sovle that. Since

3 : 5 = X : 35

Then we know

3/5 = X/35

Multiplying both sides by 35 cancels on the right

35 × (3/5) = (X/35) × 35

35 × (3/5) = X

Then solving for X

X = 35 × (3/5)

X = 21

Therefore

3 : 5 = 21 : 35
