How many numbers between 99 and 500 have an odd number of factors?

200.5

Step-by-step explanation:

The amount of numbers there are divided by 2.

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.

answer: for each 3 girls there is 2 boys . 3: 2

hope this ! (:   mark me as brainliest if you can
