Question

Quizplus · Accepted Answer

If the ratio of completed passes to attempted passes is 7 to 8, this means that for every 7 completed passes, there were 8 attempted passes. 
We can set up a proportion:

completed passes/attempted passes = 7/8

Let x be the number of completed passes:

x/16 = 7/8

Solving for x, we get:

x = (7/8) * 16

x = 14

Therefore, the quarterback completed 14 passes. We can set up a proportion to solve for the number of passes completed (let x be the number of passes completed):

completed/attempted = 7/8

x/16 = 7/8

Cross-multiplying:

8x = 112

Dividing by 8:

x = 14

Therefore, the quarterback completed 14 passes.
