Question
Simplify: $\frac{-3}{2}+\frac{5}{4}-\frac{7}{4}$
✓
Answer
$\frac{-3}{2}+\frac{5}{4}-\frac{7}{4}$
Taking the $LCM$ of the denominators: $\frac{-6}{4}+\frac{5}{4}-\frac{7}{4}$
$=\frac{-6+5-7}{4}$
$=\frac{-8}{4}$
$=-2$
Taking the $LCM$ of the denominators: $\frac{-6}{4}+\frac{5}{4}-\frac{7}{4}$
