Scott has a bag of candies. 2/5 of the candies are red. 3/10 of the candies are green. If there are 12 red candies, how many green candies are in the bag?
Let total candies = C
Given , total red candies = 2/5 of C
12= 2/5 *C
Now total candies=30
And there are given that 3/10 are green Candies of total candies.
Now , green Candies= 3/10 of total candies
= (3/10)* 30
= 90/10= 9
Therefore , total green candies=9
