Betty baked 160 wafers. She gave 80 wafers to Daniel and some wafers to Caden. She had
310 of the total wafers left.
- How many wafers did she have left?
- What fraction of the total wafers did she give to Caden?
(a)
Total number of wafers = 10 u
10 u = 160
1 u = 160 ÷ 10 = 16
Number of wafers that Betty had left
= 3 u
= 3 x 16
= 48
(b)
Number of wafers that Tina gave to Caden
= 160 - 48 - 80
= 32
Fraction of the total wafers that Betty gave to Caden
=
