Cathy baked 280 wafers. She gave 30 wafers to Ben and some wafers to Lee. She had
34 of the total wafers left.
- How many wafers did she have left?
- What fraction of the total wafers did she give to Lee?
(a)
Total number of wafers = 4 u
4 u = 280
1 u = 280 ÷ 4 = 70
Number of wafers that Cathy had left
= 3 u
= 3 x 70
= 210
(b)
Number of wafers that Tina gave to Lee
= 280 - 210 - 30
= 40
Fraction of the total wafers that Cathy gave to Lee
=
