Math 7 Lesson 46 Rates

A rate is a rtio, a comparison of two numbers.

If two apples can be purchased for 16 cents, we can write either:

$\ \frac{16\ cents}{2\ apples}$
$\frac{2\ apples}{16\ cents}$

Another way to write it is using "per"

1/8 apple per cent or 8 cents per apple
65 miles per hour $\frac{65\ miles}{1\ hour}$
25 miles per gallon $\frac{25\ miles}{1\ gallon}$
$12 per hour $\frac{12\ dollars}{1\ hour}$

Rate

The rate of speed is always found by dividing distance travelled by time.

UNIT PRICE
