plz help me

When you're dividing something by a fraction, change it to multiplying the something by the reciprocal of the fraction instead: it's much easier. The reciprocal of a fraction (a/b) is just (b/a). Also you'll need to know that (a/b) x (c/d) = (a x c) / (b x d). So:
(2/3) / (1/4) = (2/3) x (4/1) = (2x4) / (3x1) = 8/3
(1/2) x (3/7) = (1x3) / (2x7) = 3/14
(3/5) / (2/10) = (3/5) x (10/2) = (3x10) / (5x2) = 30/10 = 3
(3/4) / (4/5) = (3/4) x (5/4) = (3x5) / (4x4) = 15/16
