This just means that thefraction<span> has been reduced. For instance 4 / 6 is </span>not<span> such a </span>fraction<span>, because the top and the bottom have </span>gcf<span> = </span>2<span>, but </span>2<span> / 3 is such a </span><span>fraction</span>
Problem A,B,C, and D can be solved using 3*6=18 or 6*3=18
Reflection across the x-axis (because there is a negative)
And
Vertical compression (because a is between 0 and 1)
That will be 2.8. Hope this helps
