Mrs evans has 120 crayons and 30 pieces of paper to give to her students. what is the largest number of students she can have so that each student gets equal number of crayons and equal number of pieces of paper

The maximum number of students that will receive the paper and crayons are 30.

What is ratio?Ratio is a quantitative relation between two amounts showing the number of times one value contains or is contained within the other.

Given is Mrs. Evans who has 120 crayons and 30 pieces of paper to give to her students.

We have 120 crayons and 30 pieces of paper.

Then for 1 paper, we will have (120/30) which is equivalent to 4 crayons.

So, every student will get 1 paper and 4 crayons.

Assume that the maximum number of students that will receive the paper and crayons are [x]. Then, we can write -

x + 4x = 120 + 30

5x = 150

5x = 150

x = 30

Therefore, the maximum number of students that will receive the paper and crayons are 30.

write an algebraic expression for this word problem. An orange contains 62 calories which is x fewer calories than a nectarine. How many calories does a nectarine have?

Answer:

n = 62 + x

Step-by-step explanation:

From the problem given, it is clear that the orange has LESS calories than a nectarine. HOW much less? "x" less.

Also, orange has 62 calories. So, nectarine MUST HAVE 62 + x calories.

If we let nectarine's calories be n, we can write:

n = 62 + x
