Answer:

1) 2/7*49/-18 #multiplicative inverse of -18/49

= 7/-9

2)no, because 0.5=1/2 and the multiplicative inverse of is 2/1

3) let the no. which have to be added be x so,

-5/2+x=7/6

x=7/6+5/2

x=22/6

4)area of square =s*s

so, 1 2/3*1 2/3

= 25/9

5)let the second no. be x so,

-8/9*x=2/15

x=2/15*9/-8

x=3/-20
