Are these ratios proportional (which means equal)? 9 blue squares to 17 red squares is proportional (=) to 36 blue squares to 68 red squares
9/17 = 36/68 Is this true or false? How do you know?

So you need to answer - True or False AND how do you know.= to get full credit.

yes

9/17 *4 is 36/68.

so for proportional you need to simplify the other term and if they both result in same then they both are proportional

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.

the figures below are made out of circles, semicircles, quarter … find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations). remember that we'll also have to cut whatever areas we get in half, since we're only dealing im pretty sure that is the right answer
