Katrina drinks 0.5 gallons of water per day. Which expression shows how to find the number of cups of water she drinks in a week? (there are 16 gallons in a cup)

Answer 1

0.5 gallons / 1 day × 16 cups / 1 gallon × 7 days / 1 week

Answer 2

Answer with Step-by-step explanation:

Katrina drinks 0.5 gallons of water per day.

There are 16 gallons in a cup.

There are 1 gallons in 1/16 cup

1/2 gallons in 1/32 cup.

i.e. Katrina drinks 1/32 cups of water per day

Katrina drinks 7×1/32 cup of water in a week.

(since, 1 week=7 days)
