1/5 + 2/3 = 3/15 + 10/15 = 13/15
15/15 - 13/15 = ?
15/15 - 13/15 = ?
First, let's calculate the fraction Chelsie saved. We are told she saved 1/5 of her allowance.
Next, let's calculate the fraction Chelsie spent. We are told she spent 2/3 of her allowance.
To find the remaining fraction, we subtract the fractions Chelsie saved and spent from 1.
1 - (1/5 + 2/3)
To add the fractions, we need a common denominator. The common denominator of 5 and 3 is 15.
Now let's convert the fractions to have a common denominator:
1 - (3/15 + 10/15)
Now, add the fractions:
1 - (13/15)
To subtract the fractions, we also need a common denominator:
15/15 - 13/15
Subtracting the fractions:
2/15
Therefore, the fraction of Chelsie's allowance that remains is 2/15.
