E: 36 because the total degrees of a parallelogram is 360 and opposite angles of parallelogram’s are equal so the angles diagonal from the given ones are the same. So the corners are 3x, 2x, 3x, 2x. In total that is 10x. 360/10 = 36
When a negative number multiplies a negative number, it becomes positive
since it is multiplication, just multiply across, you do not need same denominators
5/8 x 16/25 = 80/200
80/200 = 40/100 = 20/50 = 2/5
2/5 is your answer
hope this helps
