Answer:
Jane is 14
Step-by-step explanation:
The age of each person increases by a fractional amount. In order to find Jane's age, you will need to start with Ari's age and then add the additional fractional amounts. In order to add with fractions, the denominators must be the same. In the case of Glen, you can figure his age out first:
12 + 1
5 and 6 have a common denominator of 30, so multiply the numerator and denominator by the same factor and than add:
12 = 12
+ 1
or 1
= 13
Taking Glen's age and adding the additional amount for Jane:
13 + 1
or 1
=14
