<u>Anna:</u>
1st month = 18 + = 18 inches
2nd month = 18 + = 19
3rd month = 19 + = 20
4th month = 20 + = 21
5th month = 21 + = 21
<u>Grace:</u>
Because Anna is inches shorter than Grace, we can start the count from the third month:
1st month = 20
2nd month = 21
3rd month = 21
4th month = 21 + = 22
5th month = 22 + = 23
