Question

Jason eats 10 ounces of candy in 5 days. How many pounds does he eats per day? How long will it take Jason to eat 1 pound of candy?

Answer 1

Hint:
 We will first recall the concept of unit conversion and measurement and we will apply the unitary method to solve the above question. Since we know that 1 pound is equal to 16 ounces. So, we will use the above relation between ounces and pound to solve the given question.

Complete step by step answer:
We will use the concept of unit and conversion, a unitary method to solve the above question.
We can see from the question that the amount of candy Jason eats in 5 days = 10 ounces.
So, by a unitary method we can say that amount of candy Jason eats in 1 day = $ \dfrac{10}{5} $ ounces = 2 ounces.
And, from unit and conversion, we know that 1 pound is equal to 16 ounces.
So, we can say that 1 ounce is equal to $ \dfrac{1}{16} $ pounds, (by unitary method)
Hence, 2 ounces will be equal to $ 2\times \dfrac{1}{16} $ pounds = $ \dfrac{1}{8} $ pounds.
Thus, amount of candy (in pounds) Jason eats per days = 2 ounces = $ \dfrac{1}{8} $ pounds.
Now, we know that Jason eats $ \dfrac{1}{8} $ pound of candy in 1 day.
So, the number of days Jason takes to eat 1 pound of candy = $ 1\times 8 $ days = 8 days.
Hence, Jason eats $ \dfrac{1}{8} $ pound of candy per days and he will take 8 days to eat 1 pound of candy.

Note:
 Students are required to note that we do unit conversion only between different units of measurement of the same quantities typically by multiplying them with a conversion factor. We are required to memorize the conversion factor of pounds to ounces conversion of unit otherwise we will not be able to solve the above question.
