Final answer:
To find out what percent of Andrew's at-bats were home runs, divide the number of home runs by total at-bats and multiply by 100. Andrew hit 7 home runs in 70 at-bats, which calculates to a 10% home run rate.
Step-by-step explanation:
To calculate the percentage of at-bats that were home runs for Andrew in little league, we use the following steps:
- First, take the number of home runs Andrew hit, which is 7.
- Next, divide the number of home runs by the total number of at-bats, which is 70.
- Then, to find the percentage, you multiply the fraction by 100.
Therefore, the calculation is (7 ÷ 70) × 100 = 0.1 × 100 = 10%.
So, the answer is B. 10% of Andrew's at-bats were home runs.
