Usha has 4 times as many coins as Min. Min has
23 as many coins as Hilda. If the three of them have a total of 91 coins, how many coins does Usha have?
| Usha |
Min |
Hilda |
| 4x2 |
1x2 |
|
| |
2x1 |
3x1 |
| 8 u |
2 u |
3 u |
The number of coins that Min has is repeated. Make the number of coins that Min has the same. LCM of 1 and 2 is 2.
Total number of coins that the three of them have
= 8 u + 2 u + 3 u
= 13 u
13 u = 91
1 u = 91 ÷ 13 = 7
Number of coins that Usha has
= 8 u
= 8 x 7
= 56
Answer(s): 56
