Final answer:
To determine the number of pencils that can fit in the mouth, calculate the area of one pencil and the area of the mouth, then divide the area of the mouth by the area of one pencil.
Step-by-step explanation:
The question involves calculating the number of pps (presumably meaning 'pencils' per the context) that can fit in a person's mouth. To determine this, we need to find the area of one pencil and the area of the mouth. If the pencils are 7 inches long, then the rectangular area of one pencil is 7 inches by 1 inch. The area of the mouth is 4 inches by 3 inches. To find out how many pencils can fit, divide the area of the mouth by the area of one pencil:
Number of pencils = (Area of mouth) / (Area of one pencil)
Substituting the given values into the formula, we get:
Number of pencils = (4 inches x 3 inches) / (7 inches x 1 inch)
After performing the calculation, the result is the number of pencils that can fit in the mouth.
