1. 36 min = 36/60 hr = 3/5 hour
2. 3:4 = 3x3 : 4x3 = 9:12
= 3x2 : 4x2= 6:8
3. let a's share be 2x,b's share be 3x and c's share be 5x
2x + 3x + 5x = 1200
10 x = 1200
x = 120
a's share = 2 x 120 = 240
b's share = 3 x 120 = 360
c's share = 5 x 120= 600
2. 3:4 = 3x3 : 4x3 = 9:12
= 3x2 : 4x2= 6:8
3. let a's share be 2x,b's share be 3x and c's share be 5x
2x + 3x + 5x = 1200
10 x = 1200
x = 120
a's share = 2 x 120 = 240
b's share = 3 x 120 = 360
c's share = 5 x 120= 600
