Answer:
20%
Step-by-step explanation:
Firstly, you need to know the total amount:
3 + 12 = 15
So in total there is 15 and three of them are rainsins.
Now, simply divide 100 by 15 to find the percent of one:
100 ÷ 15 = 6.666.....
Then multiply this by 3 (amount of raisins):
6.666... x 3 = ≅ 20
So she has 20% raisins!
Hope this helps!
