Answer:

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

<u><em>Molly:</em></u>

=> \frac{3}{6}*42

=> 3*7

=> 21 sweets

<u><em>Paige:</em></u>

=> \frac{2}{6}*42

=> 2*7

=> 14 sweets

<u><em>Demi:</em></u>

=> \frac{1}{6}*42

=> 7 sweets

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
