The diffrence written in simple expression form is 40/63

Step-by-step explanation:

To solve for the difference normally you have to subtract your own subscription from that of your friends,

Let's perform this operation step wise

Now your subscription is

(7w = 6)

w=6/7

Your friends own is

(9w = 2)

w=2/9

So the difference in simple form is

6/7-2/9

The LCM is 63 I. E 9*7=63

=54-14/63

=40/63
