_Brainliest for helping step by step! #1.  7:4  Difference 12 Let the no. be X and Y,  7Y=4X , Y = 4/7 X Y-X = -12  4/7X-X=-12 ,  X = 28 , Y =16 #2  5 : 22  X * Y = 440   22X = 5Y (5/22)Y*Y=440 Y =±√1936 =±44 Hence X =±10 Pair : 44 and 10, -44 and -10  #3  11:12  X+Y = 207 12X=11Y 11/12 Y+Y = 207 Y = 108, X = 99 #4   2:1 ,  X+Y = 9/4 2Y = X 2Y + Y = 9/4 Y= 3/4, X = 6/4 #5    3:4 X-Y = -1.9 4X=3Y  3/4 Y - Y = -1.9 Y = 5/38  X = 10/57
