Question

There are 384 nails in a 16-ounce jar. How many nails are there per ounce in the jar?

a. 12
b. 6,144
c. 0.0417
d. 24

Answer 1

384 nails / 16 ounces = 24 nails / ounce

Answer 2

Thinking in terms of units helps, you are going nails per ounce which is nails divided by ounces, so do that with numbers.

Answer 3

you are just simplifying the fraction, or putting it in decimal form

\[\frac{384nails}{16 ounces} = \frac{24 nails}{1ounce}\]

so for every 24 nails you have one ounce

Answer 4

they dont write the one under the fraction because it is assumed to be there

Answer 5

24?

Answer 6

yes but remember to include units

Answer 7

otherwise your answer is meaningless and you will lose marks :S
