Answer :
For the whole numbers all you have to do is put the number over one.
Because if you simplify - for example - 5/1
You'll get 5
For 1 and 3/4 you have to turn it into an improper fraction by multiplying the whole by the denominator
1 x 4
Then add the numerator
1 x 4 = 4 + 3
And since 1 x 4 = 4 + 3 = 7
7 will be your numerator replacing 3
7/4
But you must keep the denominator or the fraction wouldn't make sense
-----------------------------------------------------------------------------------------------
7 = 7/1
10 = 10/1 Hope I helped :)
1 3/4 = 7/4
------------------------------------------------------------------------------------------------
The inverse of the numbers/fractions would just be switching the numbers ...
Example :
7/1 = 1/7
10/1 = 1/10
7/4 = 4/7
The example above shows and inverse :)

7=7/1
10=10/1
1+3/4=4/4+3/4=7/4
------------------------
Inverse of 7 is 1/7.
Inverse of 10 is 1/10.
Inverse of 1+3/4 is 1/(1+3/4)=1/(7/4)=(1/1)*(4/7)=4/7.
10=10/1
1+3/4=4/4+3/4=7/4
------------------------
Inverse of 7 is 1/7.
Inverse of 10 is 1/10.
Inverse of 1+3/4 is 1/(1+3/4)=1/(7/4)=(1/1)*(4/7)=4/7.
