Answer:
Step-by-step explanation:
Let their shares be A, B and C respectively.
Given,
5A = 3B = 2C
⇒ A : B = 3 : 5
⇒ B : C = 2 : 3
The LCM of 5 and 2 is 10. Hence, we multiply the first ratio by 2 and the second by 5.
We have
A : B = 6 : 10
B : C = 10 : 15
∴ A : B : C = 6 : 10 : 15
2 Let x be amount shared
Ratio sum = 2+3=5
Betty's share = 3/5x
Ann's share = 2/5x
Also, Ann's share = 3/5x - 60
On equating Ann's share:
2/5x = 3/5x - 60
60 = 3/5x - 2/5x
60/1 = x/5 (cross multiply)
x times 1 = 60 x 5
x = $300
