Solving for small c..

So it's the answer shown in the picture, but it should be a capital W instead of a lowercase w.
The quotient of two fraction is the multiplication between the first and the inverse of the second:

So, in your case, you have

So, the question now is: which is larger, 7/10 or 3/5? To answer this question, transform the second fraction so that it will have denominator 10 as well:

So, now it is clear that
