Answer:

5/48, 3/16, .5, .75, 13
1/5, .35, 12/25, .5, 4/5
-3/4, -7/10, 3/40, 8/10
-.65, -3/8, 5/16, 2/4

Step-by-step explanation:

5/48 = 1.0291666666 | 3/16 = .1875 the rest is obvious
1/5 = .2 | 12/25 = .48 | 4/5 = .8
-3/4 = -.75 | -7/10 = -.7 | 3/40 = .075 | 8/10 = .8
-3/8 = -.375 | 5/16 = .3125 | 2/4 = .5
