Question

Jenny had a snack mix. For every 2 chocolate chips, there are 6 peanuts. If there are 108 peanuts in the mix,how many chocolate chips are in the mix

Answer 1

Use proportions. 

2 chocolate chips : 6 peanuts =     ?   chocolate chips : 108 peanuts

Find the scale factor of the information that matches. In this case it would be 108 peanuts divided by 6 peanuts. Then use this scale factor to multiply 2 chocolate chips by to get your answer.

SF: 108 ÷ 6 = 18

18 x 2 = 36 chocolate chips

2 chocolate chips : 6 peanuts =  36 chocolate chips : 108 peanuts

ANSWER: If there are 108 peanuts in the mix, there will be 36 chocolate chips in the mix.
