a. 3/4 + 9/3 - 12/6 =
........................
b. 5/3 + 2/5 - 1/3 =
............................
c. 5/4 x (-8/3) x 9/5 x ( - 3/4 ) =
............................
d. 17/9 - 6/18 - 12/3 =
...........................

Answer 1

a) 3/4 + 9/3 - 12/6 = (9+36-24)/12= 24/12=2

b) 5/3 + 2/5 - 1/3 = (25+6+5)/15= 36/15

c)5/4 x (-8/3) x 9/5 x ( - 3/4 ) = 5·(-8)·9·(-3)/4·3·5·4= 1080/1800=108/180= 54/90

d)17/9 - 6/18 - 12/3 = (34-6-72)/18= -22/9
