Question

Chelsie saves 1/5 of her allowance and spends 2/3 of her allowance at the mall. What fraction of her allowance remains?

Answer 1

1/5 + 2/3 = 3/15 + 10/15 = 13/15

15/15 - 13/15 = ?

Answer 2

To find the fraction of Chelsie's allowance that remains, we need to subtract the fraction she saved and the fraction she spent from 1.

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.

Answer 3

1/5 and 2/3 fond the common denominator of 15 so it would change 1/5 to 3/15 and 2/3 to 10/15 you add the 3/15 and 10/15 and that equals 13/15 subtract 13/15 from 15/15 or 1 and the answer is 2/15.
