notsponge [240]

solving $-8\frac{3}{4}-11\frac{1}{3}$ we get $-20\frac{1}{12}$

Step-by-step explanation:

We need to solve the following expression:

$-8\frac{3}{4}-11\frac{1}{3}$

Solving:

$-8\frac{3}{4}-11\frac{1}{3}\\ =-\frac{35}{4}-\frac{34}{3}\\=\frac{-35*3-34*4}{12}\\=\frac{-105-136}{12}\\=\frac{-241}{12}\\=-20\frac{1}{12}$

So, solving $-8\frac{3}{4}-11\frac{1}{3}$ we get $-20\frac{1}{12}$
