A = 5/6 + 4/3 x 15/8A = 5/6 + 4/3 x (3x5)/(2x4)
A = 5/6 + 4/4 x 3/3 x 5/2
A = 5/6 + 5/2
A = 5/6 + (5x3)/(2x3)
A = 5/6 + 15/6
A = 20/6
A = (2x10)/(2x3)
A = 10/3
B = 13/7 - 2/7 x 15/12
B = 13/7 - 2/7 x 15/(2x6)
B = 13/7 - 2/2 x 15/(7x6)
B = 13/7 - 15/42
B = (13x6)/(7x6) - 15/42
B = 78/42 - 15/42
B = 63/42
B = (7x3x3)/(7x2x3)
B = 3/2
C = 3 + 5/4 x (2 - 1/5)
C = 3 + 5/4 x (10/5 - 1/5)
C = 3 + 5/4 x 9/5
C = 3 + 5/5 x 9/4
C = 3 + 9/4
C = 12/4 + 9/4
C = 21/4
D = 4/7 : (2 - 3/5)
D = 4/7 : (10/5 - 3/5)
D = 4/7 : 7/5
D = 4/7 x 5/7
D = 20/49
E = (11/6 - 3/8) : (4/9 + 2/3)
E = (88/48 - 18/48) : (4/9 + 6/9)
E = 70/48 : 10/9
E = 70/48 x 9/10
E = 70/10 x 9/48
E = 7 x (3x3)/(3x16)
E = 7 x 3/16
E = 21/16
