a)
3/4 + 2/3 X 3/4
3/4 + 6/12
3/4+ 2/4 = 5/4 = 1 1/4
b)
2/3 + 3/5 X 3/2 X 4/9 - 1/3 X 1/5
2/3 + 36/90 - 1/15
2/3 + 6/15 - 1/15
2/3 + 5/15
2/3 + 1/3 = 1
c)
3/4 ( 2/1 + 1/2 ) + 1/2 X 3/4
3/4 ( 4/2 + 1/2 ) + 3/8
3/4 X 5/2 + 3/8
15/8 + 3/8 = 18/8 = 2 1/4
d)
2/5 (3/4 - 1/2 X 2/3 ) + 1/2 ( 2/3 + 5/9 )
2/5 (3/4 - 2/6 ) + 1/2 ( 6/9 + 5/9 )
2/5 (9/12 - 4/12 ) + 1/2 X 11/9
2/5 X 5/12 + 11/18
10/60 + 11/18
3/18 + 11/18 = 14/18 = 7/9
