Hello!
In this question, we are trying to find how many passes a QB completed if he attempted 20 passes.
We know:
- The ratio of completed to attempted passes is 2:5
- The QB attempts 20 passes
We will use the information above to help us solve our question.
Solve:
We know the ratio of completed to attempted passes is 2:5
The "2" represents completed passes while the "5" represents attempted passes. In other words, for every 5 passes the QB completes 2 of them.
We also know that we need to find how many passes the QB completed after throwing 20 passes. To find this, we will multiply the "5" by 4 to get "20" in our ratio for attempted passes. Note that whatever we do on one side of the ratio we do to the other side as well.
Multiply the ratio by 4.
2:5
×4
8:20
This means that the QB threw 8 completed passes out of 20 attempted passes.
Answer:
8 completed passes
