Help with a math question presented on my quiz

Published

Hello All,

I took my quiz last Thursday and til today haven't been able to figure out the answer to the question below, so I'm hoping someone can assist me.

A child is given 12mL of medication 4 times a day. The bottle hold 16oz. How many days can you give the child the medication.

A.40

B.30

C.20

D.10

My guess was C. I know you must convert the mL to oz and then divide...right?

I got 10mL

12mL 4x/day is 48mL/day

16oz converts to 480mL (16oz x 30mL/1oz)

480mL / 48mL per day = 10mL/day

I'm not too great at these myself...correct me if I am wrong!

Each day, the child needs: 12 mL x 4 doses = 48 mL.

The bottle of 16 oz = 16 oz x 30 mL/oz = 480 mL.

480 mL divided by 48 mL/day = 10 days

my answer is also 10 days

here's how:

1 oz = 30 ml

therefore 16 oz (30ml) is 480 ml

the child needs 12ml 4 times a day which means 48 ml/day

so: 480 ml

______ = 10 days

48 ml /day

hope this help and i love this site..
