Question

4 customers entered a store over the course of 16 minutes. at what rate were the customers entering the store in customers per minute?
resize the right columns to represent the unit rate.
answer

Explanation:

Step1: Calculate the rate

The rate is calculated by dividing the number of customers by the time.
$$\text{Rate}=\frac{\text{Number of customers}}{\text{Time}}$$
Here, the number of customers is \(4\) and the time is \(16\) minutes.
So, \(\text{Rate}=\frac{4}{16}\)

Step2: Simplify the fraction

Simplify \(\frac{4}{16}\) by dividing both the numerator and the denominator by their greatest - common divisor.
The GCD of \(4\) and \(16\) is \(4\).
\(\frac{4\div4}{16\div4}=\frac{1}{4}\)

Answer:

$\frac{1}{4}$ customers per minute
