Example:

Problem: Emily has $7.50 and wants to buy 5 pens. If each pen costs the same amount, how much does each pen cost?

Solution: Divide $7.50 by 5.

\[ \frac{7.50}{5} = 1.50 \]

Each pen costs $1.50.

in 15 hours bob makes 7.5 boxes. how many boxes can he make in one hour?
so 15 hours=7.5 boxes divide both sides by 15 to get hours 1 hour=7.5/15 answer is 1 hour=0.5 boxes

The length of the crust of each slice is approximately 6.28318 inches.
The real-world problem can be described as follows:
A large pizza with a diameter of 16 inches is cut into 8 equal slices. If a person wants to know the length of the crust of each slice, how long is the crust of each slice? (Assume the crust is the circumference of the pizza.)
First, we need to calculate the circumference of the entire pizza using the formula for the circumference of a circle, which is C = π × d , where d is the diameter of the circle.
Given that the diameter d is 16 inches, the circumference C of the entire pizza is:
C = π × d = π × 16
Now, we know that π is approximately 3.14159, so:
C = 3.14159 × 16
C = 50.26544
The pizza is cut into 8 equal slices, so to find the length of the crust for each slice, we divide the total circumference by the number of slices:
Length of crust per slice = 8 C ​ = 8 50.26544 ​
Now, we perform the division:
Length of crust per slice = 6.28318
Therefore, the length of the crust of each slice is approximately 6.28318 inches.
In summary, the crust of each of the 8 slices of the pizza is approximately 6.28318 inches long. This is the result of dividing the total circumference of the pizza by the number of slices.
