Question

A box of ground nutmeg weighs 1 1/3 ounce. If there are 20 teaspoons of nutmeg in the box, how much does one teaspoon of nutmeg weigh?
1/15 ounce
1/20 ounce
1/60 ounce
4/3 ounce

Answer 1

we know that

a) A box of ground nutmeg weighs $1 1/3$ ounces

b) There are $20$ teaspoons of nutmeg in the box

Step 1

Convert mixed number to an improper fraction

$1\frac{1}{3} \ ounces= \frac{1*3+1}{3}= \frac{4}{3}\ ounces$

Step 2

By proportion

Find the weight of one teaspoon

$\frac{(4/3)}{20} \frac{ounces}{teaspoons} =\frac{x}{1} \frac{ounces}{teaspoon} \\ \\x= \frac{4}{20*3}\\ \\x= \frac{4}{60}\ ounces\\\\x=\frac{1}{15}\ ounces$

therefore

the answer is the option

$\frac{1}{15}\ ounces$

Answer 2

We can find out what the answer is by dividing the weight in ounces with the number of teaspoons.

1 1/3 = 4/3
(4/3)/20 = 4/60
4/60 = 1/15

The answer is 1/15 ounce
