a) 3/9= 0.333333333333 but you can just say 0.3
b) 4/3= 1.333333333333 but you also can say 1.33 or just 1.3
2)
a) 21/8, 21 over 8 if you solve you would get 2.625
b) 7(divide sign)4, which is also 7/4, if you solve you would get 1.75
c) 4/9 , 4 over 9 if you solve you would get 0.444444444 which is 0.4
d) 9/7, 9 over 7, if you solve it would be 1.285 which is 1.3
It would be: 6 ( 6- 4)
= 6 ( 2)
= 12
So, Your Answer would be 12
