Well, the numerator is the number on top, so in the fraction 3/5, 3 is the numerator. To find the equation with a denominator of 30 that is equivalent, find what the difference is. 30/5 = 6. So now, multiply the numerator by 6. 6 * 3 = 18. The new fraction is 18/30. The numerator is 18. Hope this helps!

Let x be the angle 
Complement of x is (90 degrees-x)
Supplement of x is (180 degrees-x)
4•(90-x)= 2/3(180-x) 
3•4(90-x)=2(180-x) 
1080-12x=360-2x
1080-360=12x-2x
720=10x 
720/10= x
So x = 72 degrees
