Question

21p=15+12+Mr.Roberts,Mrs.Clark,andMs.Jones buy six pizzas to share equally between all of their students. p=15+12+21/6

Which equation can be used to find the tion of a pizza, p, each student receives?

a) 1/15+12+21
b) 15+12+21/6
c) 1/6
d) 15+12+21/6
​

Answer 1

The correct equation to find the portion of pizza, p, each student receives is d) 15 + 12 + 21 / 6, as it represents dividing the total number of pizzas (6) by the sum of students (15 + 12 + 21).

Step-by-step explanation:

The student is trying to find the correct equation to calculate the portion of pizza, p, each student receives when Mr. Roberts, Mrs. Clark, and Ms. Jones buy six pizzas to share equally among their students. The correct equation will involve dividing the total number of pizzas by the sum of the students. The number of pizzas is represented by 6, and the total number of students is represented by the sum of three numbers, 15 + 12 + 21. To find the portion of pizza each student receives, we divide the number of pizzas by the total number of students.

The correct equation to represent the allocated portion of pizza, p, for each student is:

d) 15 + 12 + 21 / 6

This is because you divide the total number of pizzas (6) by the total number of students (15 + 12 + 21) to find what each student receives (p).
