Before |
3x3 = 9 u |
4 u |
+ 12 |
168 |
Change |
- 1x3 = - 3 u |
- 3 u |
- 9 |
|
After |
2x3 = 6 u |
1 u |
+ 3 |

(a)
9 ÷ 3 x 4 = 12
9 ÷ 3 x 1 = 3
Total mass of pork and venison bought
= 9 u + 4 u + 12
= 13 u + 12
13 u + 12 = 168
13 u = 168 - 12
13 u = 156
1 u = 156 ÷ 13 = 12
Mass of venison bought
= 4 u + 12
= 4 x 12 + 12
= 48 + 12
= 60 kg
(b)
Mass of pork bought
= 9 u
= 9 x 12
= 108 kg
Answer(s): (a) 60 kg; (b) 108 kg
