as (-5/10) and secondly there are some questions in which we did this procedure

(2 * 5 / 2) - (3 * 1 / 4)

( 9 / 2 ) - (5 / 4 )( 9 - 5 / 4 )

(4 / 4 ) = 1

is this correct in some questions we also use this method?

Yes, a fraction can be negative! -1/2 -3/4

But depending on how you write the equations the '-' sign might be for negative or subtraction.

12*(-3/4) or 12(-3/4) is twelve times negative three-quarters

12-3/4 is twelve minus three-quarters

Also in your question here it is not clear what your question is.

In the last line (4/4) is indeed equal to 1.

But in the first two lines what are you asking?

Is it what those two lines are equal to? If so...

2*(5/2) - 3*(1/4) = (10/2) - (3/4) = (20/4) - (3/4) = 17/4 = 4 1/4

(9/2) - (5/4)(9- 5/4) = (9/2) - (5/4)(36/4 - 5/4)

= (9/2) - (5/4)(31/4) = (18/4) - (155/4) = -137/4 = -34 1/4
