Question

There are $25$servings in a $30.2$-ounce jar of peanut butter. How many ounces of peanut butter are there in $1$ serving?

Answer 1

As we know that the above given question is a word problem. A problem is a mathematical question written as one sentence or more describing a real life scenario where that problem needs to be solved by the way of mathematical calculation. We can solve the given problem by applying the unitary method i.e. to find the value of a single unit from the value of a multiple and hence we get the value of a multiple.

Complete step by step solution:
We need to first understand the requirement of the question which is the ounces of peanut butter in $1$ serving. Here we have $30.2$-ounce jar of peanut butter in $25$servings. We will apply the unitary method.
$25$servings have $30.2$ ounces of peanut butter. So in $1$ serving the ounce of butter is
$\dfrac{{30.2}}{{25}} = \dfrac{{302}}{{25*10}}$, it gives $1.208$ ounces of peanut butter in one serving.

Hence the answer is there are $1.208$ ounces of peanut butter in $1$ serving.

Note: We should always be careful what the question is asking i.e. to find the single unit value or to find the value of various multiple from single units. Based on the requirement and by observing all the necessary information that is already available in the question we gather the information and then create an equation or by unitary method whichever is applicable, then we solve the problem and then verify the answer by putting the value in the problem and see whether we get the same answer or not.
