Question

find the unit rate.\
\\(\frac{48\text{ cm}}{4\text{ min}}\\)\
\\(\frac{48\div?}{4\div 4}=\frac{?}{1}\\)\
\\(\frac{?\text{ cm}}{1\text{ min}}\\)\
divide.\
\\(\frac{48\div \square}{4\div 4}=\frac{\square}{1}\\)

Explanation:

Step1: Identify divisor for denominator

To get denominator 1, divide 4 by 4. So we use 4 as the divisor for numerator too.

Step2: Compute numerator division

Calculate $48 \div 4 = 12$

Step3: Form the unit rate

Set up the simplified fraction with denominator 1.
$\frac{48 \div 4}{4 \div 4} = \frac{12}{1}$

Answer:

The missing values are 4 and 12, so the unit rate is $\frac{12\ \text{cm}}{1\ \text{min}}$ or 12 cm per minute.
