310 of the total scones left.
- How many scones did she have left?
- What fraction of the total scones did she give to David?

Total number of scones = 10 u
10 u = 150
1 u = 150 ÷ 10 = 15
Number of scones that Gillian had left
= 3 u
= 3 x 15
= 45
(b)
Number of scones that Tina gave to David
= 150 - 45 - 60
= 45
Fraction of the total scones that Gillian gave to David
