Before |
5x3 = 15 u |
4 u |
+ 12 |
126 |
Change |
- 1x3 = - 3 u |
- 3 u |
- 9 |
|
After |
4x3 = 12 u |
1 u |
+ 3 |
|
(a)
9 ÷ 3 x 4 = 12
9 ÷ 3 x 1 = 3
Total mass of venison and pork bought
= 15 u + 4 u + 12
= 19 u + 12
19 u + 12 = 126
19 u = 126 - 12
19 u = 114
1 u = 114 ÷ 19 = 6
Mass of pork bought
= 4 u + 12
= 4 x 6 + 12
= 24 + 12
= 36 kg
(b)
Mass of venison bought
= 15 u
= 15 x 6
= 90 kg
Answer(s): (a) 36 kg; (b) 90 kg
