sarah, natasha and richard share some sweets in the ratio 5:2:4. sarah gets 60 sweets. how many did richard get?​
Sindrei [870]

Answer:

48 sweets

Step-by-step explanation:

5:2:4

Sarah: 5

Natasha:2

Richard:4

To find out how many sweets Richard got, we need to use 60 as the lcm. Since, we have a definite constant of 60 we need to divide it by the presiding ratio.

60/5 = 12

That means for a ratio of 1, everyone in the group recieves 12.

Now, we plug it in for each of the members.

5x = Sarah

2x = Natasha

4x = Richard

Sarah = 60 sweets

Natasha = 24 sweets

Richard = 48 sweets
