Molly, Paige and Demi share 42 sweets in the ratio 3 : 2:1 Work out the number of sweets that each of them receives.

Add the ratios: 3+2+1= 6

Divide total treats by total ratio:

42/6 = 7

Now multiply each separate ratio by that:

Molly = 3x7 = 21

Paige = 2x7 = 14

Demi = 1x7 = 7

Molly gets 21, Paige gets 14 and Demi gets 7

Step-by-step explanation:

Total = 42

Ratio = 3:2:1

Total Parts = 3+2+1 = 6

Molly:

=>

=> 3*7

=> 21 sweets

Paige:

=>

=> 2*7

=> 14 sweets

Demi:

=>

=> 7 sweets
