Can you please help me with the approach regarding with this question? Although I tried to solve it but not able to get an answer.

To make a tart for 6 people, Karin needs 1 112 lb. of

peaches and 213 cup of apricot jam. How much does

she need for 20 people?

Official Answers: 5 lbs peaches, 2 2/9 cups apricot jam.

My approach:

As 1 lb= 16 ounces

1 cup= 8 ounces

so

3/2 lb= 24 ounces

and

24 ounces= 3 cups of peaches

Total= 3 cups of peaches+ 2/3 cup of jam

= 11/3 cup

Now, using proportion: 6/20= 11/3/x

After this step, my answer is 73.3/6.

Could you please check in which step I got wrong?
