Step-by-step explanation:

first we turn ur mixed number into an improper fraction

1 1/4 = 5/4

the reciprocal of 5/4 can be found by just flipping it....so the reciprocal is gonna be 4/5

so 1 1/4 subtracted from its reciprocal is :

4/5 - 5/4 =

16/20 - 25/20 =

- 9/20 <====

Answer 2

We want to subtract (1 1/4) from its reciprocal, we will see that the correct option is A; -9/20

To find the reciprocal of the given number, first we write it as a fraction, we have:

1 + 1/4 = 4/4 + 1/4 = 5/4

The reciprocal is just the inverse, so the numerator becomes the denominator and the denominator becomes the numerator, we have that the reciprocal is:

r = 4/5

Now we subtract the original number:

4/5 - 5/4 = 16/20 - 25/20 = -9/20

So the correct option is A.
