Question

express the following as a rational number 7/12 - 5/6 + 1/8 - 5/12​

Answer 1

Answer:

$- \frac{13}{24}$

Step-by-step explanation:

$\frac{7}{12} - \frac{5}{6} + \frac{1}{8} - \frac{5}{12} \\ \\ = \frac{7}{12} - \frac{5}{12} - \frac{5}{6} + \frac{1}{8} \\ \\ = \frac{7}{12} - \frac{5}{12} - \frac{10}{12} + \frac{1}{8} \\ \\ = \frac{7 - 5 - 10}{12} + \frac{1}{8} \\ \\ = - \frac{8}{12} + \frac{1}{8} \\ \\ = - \frac{16}{24} + \frac{3}{24} \\ \\ = - \frac{13}{24}$
