Before |
3x3 = 9 u |
4 u |
+ 8 |
99 |
Change |
- 1x3 = - 3 u |
- 3 u |
- 6 |
|
After |
2x3 = 6 u |
1 u |
+ 2 |
|
(a)
6 ÷ 3 x 4 = 8
6 ÷ 3 x 1 = 2
Total mass of venison and chicken bought
= 9 u + 4 u + 8
= 13 u + 8
13 u + 8 = 99
13 u = 99 - 8
13 u = 91
1 u = 91 ÷ 13 = 7
Mass of chicken bought
= 4 u + 8
= 4 x 7 + 8
= 28 + 8
= 36 kg
(b)
Mass of venison bought
= 9 u
= 9 x 7
= 63 kg
Answer(s): (a) 36 kg; (b) 63 kg
