Answer:
Answer is 49
Step-by-step explanation:
Add all the ratios up you get 21 so then you divide 147 by 21 thus giving you 1 ratio = 7 respectively, and we know the ratio of the red is 7 because it's stated red, blue, and green -> 7,6,8. So then 7 * 7 = 49. And to confirm you can do (7*7)+(6*7)+(8*7) which should equal 147
The best thing to do is to find the cost of one sweet, and to do this, divide 42 by 7.
42/7= 6
Therefore, one sweet costs 6p.
To find the cost of 8 sweets, you've got to multiply 6 by 8, and this gives you 54p.
Therefore, 8 sweets cost 54p
This is basically just finding unit rate and multiplying.

Complete question :
At camp in Green Bay, Wisconsin, 7/9 of the participants were from Wisconsin. Of that group 3/5 were 12 years old. What fraction of the group was from Wisconsin and 12 years old?
Answer:
7/ 15
Step-by-step explanation:
Fraction from Wisconsin = 7/9
Fraction who are 12 years old = 3/5
Fraction who are from Wisconsin and 12 years old
(Fraction from Wisconsin * Fraction who are 12 years old)
(7 / 9 * 3/ 5)
= (7 * 3) / (9 * 5)
= 21 / 45
= 7 / 15
