Question

How do you find the unit rate of \[\$ 10.99\] for 12 slices of pizza?

Answer 1

Hint: Here in this question we have to find the value of one slice of a pizza, as they have given the cost of 12 slices of pizza. By using the simple arithmetic operations we determine the value of a one slice of a pizza. Hence we obtain the required solution for the given question.

Complete step-by-step answer:
In mathematics we have different four kinds of arithmetic operations namely addition which adds the numbers, subtraction which subtracts the numbers, multiplication which multiply the numbers and division which divides the number.
The data from the given question is
The total cost of 12 slices of pizza is \[\$ 10.99\]
now here we have to find the value of or cost of one slice of pizza
Therefore the value of one slice of pizza is \[\dfrac{{\$ 10.99}}{{12}}\]
when we divide the 10.99 by 12 we get less than 1 as the answer i.e 0.9518
Therefore the value of 1 slice of pizza is \[\$ 0.9158\]. The unit will be dollar since in the question we have the unit as dollar itself. we should not forget to write the unit.
So, the correct answer is “\[\$ 0.9158\]”.

Note: When the question involves finding the cost of one term usually we use the division. To divide the number we must know the tables of multiplication which makes it easy to simplify and determine the value. If we don’t know the tables of multiplication we may go wrong in obtaining the answer.
