1 u |
1 u + 8 |

| Value |
4 |
2 |
|
| Total value |
4 u |
2 u + 16 |
6 u + 16 |
Number of hippopotamuses = 1 u
Number of flamingos = 1 u + 8
Number of hippopotamuses' legs
= 4 x 1 u
= 4 u
Number of flamingos' legs
= 2(1 u + 8)
= 2 u + 16
Total number of legs
= 4 u + 2 u + 16
= 6 u + 16
6 u + 16 = 160
6 u = 160 - 16
6 u = 160 - 16
6 u = 144
1 u = 144 ÷ 6 = 24
Number of flamingos
= 1 u + 8
= 24 + 8
= 32
Answer(s): 32
