c.
The yellow onion is 1.56 ounces heavier than the red onion.
d.
The yellow onion is 2.08 ounces heavier than the red onion.

Answer 1

Convert to ounces. The yellow onion is 0.59 lb = 0.59·16 = 9.44 oz. The red onion is 208.65 g = 208.65/(453.5924/16) ≈ 7.36 oz. Difference = 9.44 − 7.36 = 2.08 oz.

Answer: d.
