Using proportions, it is found that she needs 4 consecutive hits to raise her batting average to .400.
<h3>What is a proportion?</h3>A proportion is a fraction of a total amount.
Hence, the batting average is given by the <u>number of hits divided by the number of at-bats</u>.
If she gets x consecutive hits, she will have 8 + x hits in 25 + x at-bats, for an average of 0.400, hence:
8 + x = 10 + 0.4x
0.6x = 2
x = 3.33
Rounding up, she needs 4 consecutive hits to raise her batting average to .400.
