Gem bought some eggs to bake cakes for a party. If she used 5 eggs for each cake, she would be short of 11 more eggs to bake all cakes. If she used 9 eggs for each cake, she would be short of 51 more eggs.
- How many cakes did she bake?
- How many eggs did Gem buy?
(a)
Small difference
= 9 - 5
= 4
Big difference
= 51 - 11
= 40
Number of cakes that Gem bought
= 40 ÷ 4
= 10
(b)
Number of eggs that Gem bought
= 10 x 5 - 11
= 50 - 11
= 39
Answer(s): (a) 10; (b) 39
