Question

Leah is sending out 32 party invitations. She gives 5 invitations to her Mom to give to family members. Leah mails a third of the rest. Write a numerical expression to describe how many invitations Leah has already mailed.

Answer 1

9 of 32 invitations were mailed

fraction = 9/32

Decimal = this can be derived by dividing 9 by 32 = 0.28

Percentage = this can be derived by multiplying the decimal by 100 = 28%

Explanation:

Number of invitations mailed = 1/3 x (total invitation - invitation mom delivered)

1/3 x (32 - 5)

1/3 x (27)

= 9

This figure can be expressed as a fraction
