37 of the total shortbreads left.
- How many shortbreads did she have left?
- What fraction of the total shortbreads did she give to Zeph?
(a)
Total number of shortbreads = 7 u
7 u = 280
1 u = 280 ÷ 7 = 40
Number of shortbreads that Lucy had left
= 3 u
= 3 x 40
= 120
(b)
Number of shortbreads that Tina gave to Zeph
= 280 - 120 - 50
= 110
Fraction of the total shortbreads that Lucy gave to Zeph
