(x, y) ⇒ (y, -x) . . . . . . . rotation 270° CCW

This means the points are moved to ...

A(-2, 1) ⇒ A'(1, 2)

B( 1, 2) ⇒ B'(2, -1)

C(-2, 4) ⇒ C'(4, 2)

3/4 and 5/6
Now, you have to find the common denominator to compare the two fractions properly. Let’s see... 12 can be divided by both 4 and 6. So we’re going to convert both denominators to 12.

3*3= 9 and 4*3=12 so 3/4 = 9/12

5*2= 10 and 6*2=12 so 5/6 = 10/12

Bryan’s brother ate more peach.
