Before |
2x3 = 6 u |
4 u |
+ 16 |
36 |
Change |
- 1x3 = - 3 u |
- 3 u |
- 12 |

After |
1x3 = 3 u |
1 u |
+ 4 |

(a)
12 ÷ 3 x 4 = 16
12 ÷ 3 x 1 = 4
Total mass of chicken and venison bought
= 6 u + 4 u + 16
= 10 u + 16
10 u + 16 = 36
10 u = 36 - 16
10 u = 20
1 u = 20 ÷ 10 = 2
Mass of venison bought
= 4 u + 16
= 4 x 2 + 16
= 8 + 16
= 24 kg
(b)
Mass of chicken bought
= 6 u
= 6 x 2
= 12 kg
Answer(s): (a) 24 kg; (b) 12 kg
