Finding and using unit rates
A unit rate compares a quantity to one unit of another quantity. Dividing the total amount by the number of units gives an amount per one. The units tell what the quotient means.
A method you can use
- Write the comparison with units in the intended order.
- Divide numerator and denominator by the denominator’s value to make it one.
- Use the unit rate to compare options or scale to a new quantity.
