Is a unit fraction always in simplest form?

A unit fraction is a fraction with a numerator equal to 1. With that being said, i think it is ok for us to say they are in simplest form. Besides, you can't divide anything by 1 in order to make it smaller.

b) k’(6, 4); l’(3, 3)

step-by-step explanation:

a 270° clockwise rotation maps every point (x, y) to (y, -x). (it negates the x-coordinate and then switches it and the y-coordinate.)

this means the endpoints of the side congruent to kl, k' and l', would be mapped as:

k'(-4, 6)→(6, 4)

l'(-3, 3)→(3, 3)
