Question

A restaurant serves a 20-ounce steak. How much does the steak weigh in pounds and ounces?

Answer 1

Hint: To solve the above problem we need to know the value of 1 pound. The value of 1 pound is 16 ounces. Ounce is also defined as a unit of weight of one sixteenth of a pound. Using this relation we can solve the above problem.

Complete step by step answer:
Given a restaurant serves 20-ounce steak. We need to convert it into pounds and ounces. We know that $$1pound=16ounces$$
Now we need to convert our steak into pounds. Our steak weighs 20 ounces. So, we need to convert 20 ounces to pounds. To convert 20 ounces to pounds. We need to divide 20 ounces with 16 ounces since $$1pound=16ounces$$and the remainder will remain as ounces.
$$\Rightarrow {\displaystyle \frac{20}{16}}$$
The quotient will be 1 and the remainder will be 4.
Since the quotient is 1. We can write 20 ounces will contain 1 pound and the remainder is 4. So, it contains 4 ounces too.
So, 20 ounces contains 1 pound and 4 ounces. That means our steak also weighs 1pound and 4 ounces. Since our steak weighs 20 ounces.
$$\therefore$$ The steak weighs 1 pound and 4 ounces.

Note:
In order to solve these types of problems, we need to have knowledge over the relation between pounds and ounces. While dividing we have to check whether we are dividing it with pounds or ounces. If we want to convert ounces to pounds then we need to divide ounces with pounds.
