Question

5/8 + 15/6 - 4/12×27/8​

Answer 1

Answer:

$\frac{5}{8} + \frac{15}{6} - \frac{4}{12} \times \frac{27}{8}$

$\frac{5 \times 3}{8 \times 3} + \frac{15 \times 4}{6 \times 4} = \frac{15}{24} - \frac{60}{24} = \frac{ - 45}{24}$

$\frac{ - 45}{24} - \frac{4}{12} \times \frac{27}{8}$

$\frac{ - 45}{24} - \frac{4 \times 2}{12 \times 2} = \frac{ - 45}{24} - \frac{8}{24} = \frac{ - 53}{24}$

$\frac{ - 53}{24} - \frac{4}{12} \times \frac{27}{8}$

$\frac{ - 53}{24} - \frac{4 \times 2}{12 \times 2} = \frac{ - 53}{24} - \frac{8}{24} = \frac{ - 61}{24}$

$\frac{ - 61}{24} \times \frac{27}{8}$

$\frac{ - 61}{24} \times \frac{27}{8} = \frac{( - 61) \times 27}{24 \times 8} = \frac{ - 1647}{192}$
