Question

Find the following sum -
5/12+3/16+7/-8

Answer 1

Answer:

$-\frac{13}{48}$

Step-by-step explanation:

The Given Mathematical Statement is:

   $\frac{5}{12}+\frac{3}{16} +\frac{7}{-8}$

= $\frac{5}{12}+\frac{3}{16} -\frac{7}{8}$

= $\frac{(5*\frac{48}{12})+(3*\frac{48}{16}) -(7*\frac{48}{8} ) }{48}$

= $\frac{(5*4)+(3*3)-(7*6)}{48}$

= $\frac{20+9-42}{48}$

= $\frac{-13}{48}$

= $-\frac{13}{48}$     (ans)
