Answer :

(11+7/8)/(4+3/4)

=(88/8+7/8)/(16/4+3/4)

=(95/8)/(19/4)

=(95/8)*(19/4)⁻¹

=(95/8)*(4/19)

=(95*4)/(4*2*19)

=95/38

=5/2
okay
first make them to improper fractions like
95/8 divided by 19/4 double check by dividing them
to divide remember to flip the latter number
aka
95/8 multiplied by 4/19
95             4
---  ****    ---          Divide 95 by 19, simplifies to 5 and 19 becomes 1. Simplify 4 
8              19         and 8. 8 becomes 2. After simplifying, answer's 5/2.
