Question
Subtract: $-\frac{4}{7}$ from $-\frac{6}{11}$
✓
Answer
$\begin{aligned} & -\frac{4}{7} \text { from }-\frac{6}{11} \\ & =-\frac{6}{11}-\left(-\frac{4}{7}\right)=-\frac{6}{11}+\frac{4}{7} \\ & =\frac{-6 \times 7}{11 \times 7}-\frac{4 \times 11}{7 \times 11} \\ & (\text { LCM of } 7 \text { and } 11=77) \\ & =-\frac{42}{77}+\frac{44}{77}=-\frac{42+44}{77}=\frac{2}{77}\end{aligned}$
