| Number |
1 u |
1 u + 7 |
|
| Value |
4 |
2 |
|
| Total value |
4 u |
2 u + 14 |
6 u + 14 |
Number of hippopotamuses = 1 u
Number of storks = 1 u + 7
Number of hippopotamuses' legs
= 4 x 1 u
= 4 u
Number of storks' legs
= 2(1 u + 7)
= 2 u + 14
Total number of legs
= 4 u + 2 u + 14
= 6 u + 14
6 u + 14 = 116
6 u = 116 - 14
6 u = 116 - 14
6 u = 102
1 u = 102 ÷ 6 = 17
Number of storks
= 1 u + 7
= 17 + 7
= 24
Answer(s): 24
