Question

Marcie cooked dinner for herself. The original recipe has a serving size of 3 and requires three and three sevenths' pounds of chicken. How many pounds of chicken will be needed for a single serving?

Answers:
A: 1 1/7
B: 9 3/7
C: 2/49
D: 3/7

Answer 1

A: 1 1/7

Explanation:

serving size of 3 requires 3 3/7 pounds of chicken,

Now, for a single serving we divide by 3 to get,

3/3 3/(3)(7) = 1 1/7

Answer 2

The number of pounds for 3 people is given by:
3루= 3+무=½
Hence, for one person, the number of pounds can be divided by three(multiplied by 1/3), hence:
24 divided by 21 has a quotient of 1 and remainder of 3, hence as a mixed number, the amount is:
one and three seventh pounds.
