See a solution process below:

First, we can rewrite the expression as:

#9/10 - 7#

We can now convert the integer to a fraction with a common denominator by multiplying it by the appropriate form of #1#:

#9/10 - (10/10 xx 7) =>#

#9/10 - 70/10#

We can subtract the two numerators over the common denominator:

#9/10 - 70/10 => (9 - 70)/10 =>#

#-61/10#
