Tammy baked 220 wafers. She gave 50 wafers to Michael and some wafers to Flynn. She had
511 of the total wafers left.
- How many wafers did she have left?
- What fraction of the total wafers did she give to Flynn?
(a)
Total number of wafers = 11 u
11 u = 220
1 u = 220 ÷ 11 = 20
Number of wafers that Tammy had left
= 5 u
= 5 x 20
= 100
(b)
Number of wafers that Tina gave to Flynn
= 220 - 100 - 50
= 70
Fraction of the total wafers that Tammy gave to Flynn
=
