Question

verify the following :. -3/4+7/-8=7/-8+(-3/4)

Answer 1

Hey friend,
Here is the answer you were looking for:
$- \frac{3}{4} + \frac{7}{ - 8} = \frac{7}{ - 8} + ( - \frac{3}{4} ) \\ \\ - \frac{3}{4} + ( - \frac{7}{8} ) = - \frac{7}{8} - \frac{3}{4} \\ \\ - \frac{3}{4} - \frac{7}{8} = - \frac{7}{8} - \frac{3}{4} \\ \\ \frac{ - 3 \times 2 - 7 \times 1}{8} = \frac{ - 7 \times 1 - 3 \times 2}{8} \\ \\ \frac{ - 6 - 7}{8} = \frac{ - 7 - 6}{8} \\ \\ = \frac{ - 13}{8} = \frac{ - 13}{8}$

Hence verified...


Hope this helps!!!

hola

==============================

we should verify  the following :. -3/4+7/-8=7/-8+(-3/4)

=> l.h.s   

=>$\frac{-3}{4} + \frac{7}{-8}$

=> $\frac{-3}{4} + \frac{-7}{8}$

  =>          $\frac{-6}{8} + \frac{-7}{8}$

=>$\frac{-13}{8}$

r.h.s

=>7/-8+(-3/4)

=>$\frac{-7}{8} - \frac{3}{4}$

=>$\frac{-7}{8} - \frac{6}{8}$

=>$\frac{-13}{8}$

------------------------------

l.h.s = r.h.s

∴ -3/4+7/-8=7/-8+(-3/4)
