34 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 = 4 u
4 u = 180
1 u = 180 ÷ 4 = 45
Number of shortbreads that Natalie had left
= 3 u
= 3 x 45
= 135
(b)
Number of shortbreads that Tina gave to Zeph
= 180 - 135 - 30
= 15
Fraction of the total shortbreads that Natalie gave to Zeph
