Question

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

Answer 1

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

One teaspoon of nutmeg weighs 1 1/15 ounces.

Answer 2

Answer: $\dfrac{1}{15}$ ounces

Step-by-step explanation:

Given : A box of ground nutmeg weighs $1\dfrac{1}{3}$ ounces.

We can write $1\dfrac{1}{3}$  as $\dfrac{3\times1+1}{3}=\dfrac{4}{3}$

If there are 20 teaspoons of nutmeg in the box, then by Unitary method , we have

20 teaspoons =$\dfrac{4}{3}$ ounces

Divide both the sides by 20 , we get

1 teaspoon =$\dfrac{4}{3\times20}$ ounces

i.e. 1 teaspoon =$\dfrac{1}{3\times5}$ ounces

i.e. 1 teaspoon =$\dfrac{1}{15}$ ounces

Hence, one teaspoon of nutmeg weigh $\dfrac{1}{15}$ ounces.
