On the first one I know it is not Noah so please don´t put Noah. Also make sure to explain please

Step-by-step explanation:

For the question 5, Noah is right, as 75/100 x 10 = 7.5, and 25/100 x 30 = 7.5

So both of then have equal amount, therefore, Noah is right.

d. is the correct answer

step-by-step explanation:

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.
