Question
Subtract: $\frac{-9}{7}\text{ from }-1$
✓
Answer
$\frac{-9}{7}\text{ from }-1$$\frac{-1}{1}=\frac{-1\times7}{1\times7}=\frac{-7}{7}$
$\therefore-1-\Big(\frac{-9}{7}\Big)=-1+\frac{9}{7}$
$=\frac{-7}{7}+\frac{9}{7}=\frac{-7+9}{7}=\frac{2}{7}$
$\therefore-1-\Big(\frac{-9}{7}\Big)=-1+\frac{9}{7}$
$=\frac{-7}{7}+\frac{9}{7}=\frac{-7+9}{7}=\frac{2}{7}$
