You can't do anything because they aren't the same term
9:11, 9/11 are the only ones because girls are first
"4 7/8 yards is almost 5 yards. To make certain that you have enough fabric, round up. <span>3 dresses at 5 yard each is 15 yards."</span>
To rotate a figure
90 degrees(-y,x)
180 degrees(-x,-y)
270 degrees(y,-x)
If your original point is (1,2) or example and you want to rotate it say 270 degrees the final point would be (2,-1)
Hope this helped!!!!!
