Answer:
1/6 is your answer.
Explanation:
Heres why. First you need to make 1/2 into a fraction that can be reduced by 3. 9/18 can be divided by 3 and 9/18÷3/1=3/18. This is how much of the whole loaf each friend can get. Also, you can reduce this fraction to 1/6 since 3/18 can be divided into each other. Hope I helped!
