Does anyone know how to do Unit Rate?

Blake burns 4 1/2 calories in 2/3 of a minute riding his bike. What is Blake's unit rate in calories per minute?

3/4 ÷ 3/4

step-by-step explanation:

basically divide any proper fraction with itself to fit the criteria.

so if we are using 3/4, then:

3/4 ÷ 3/4 = 1

so 1 is the quotient.

and the numerators for both these fractions is 3.   and if we divide the numerators:

3 ÷ 3 = 1

we see that quotient is equal to our original quotient as well.
