How many ways are there to choose a committee of 7 people from a group of 10 people? 720 120 840 5040

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

3 ÷ 3 = 1

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