**Benchmarks** can be used to estimate the sum or difference of fractions.

Benchmarks are fractions that are easier to

add or subtract, like $0,\frac{1}{4},\frac{1}{2},\frac{3}{4},$ and $1$.

Use benchmarks to estimate the difference.

$\frac{1}{12}$ can be estimated as $0$.

$\frac{8}{11}$ can be estimated as $\frac{3}{4}$.

So, the sum is closer to $\frac{3}{4}$ than $0$.
