Mrs Rael baked some shortbreads. She gave
38 of the shortbreads to her nephew and
320 of the remainder to her uncle. Given that she gave 18 less shortbreads to her uncle than her nephew. How many shortbreads did
she bake at first?

| 12 u |
3 u |
17 u |
32 u |
Number of less shortbreads that Mrs Rael gave to her uncle than her nephew
= 12 u - 3 u
= 9 u
9 u = 18
1 u = 18 ÷ 9 = 2
Number of shortbreads that Mrs Rael baked at first
= 32 u
= 32 x 2
= 64
Answer(s): 64
