Question

subtract the sum of - 3 by 10 and 5 by 8 from the sum of 4/15 and 2/-5​

Answer 1

$\yellow{\bf{Sum\:of\:\dfrac{-3}{10} and \frac{5}{8}}}$

$\red{\tt{\frac{-3}{10} + \frac{5}{8}}}$

$\red{\tt{=\frac{-12 + 25}{40}}}$

$\red{\tt{=\frac{13}{40}}}$

$\yellow{\bf{Sum\:of\:\dfrac{4}{15} and \frac{2}{-5}}}$

$\green{\tt{\frac{4}{15} + \frac{2}{-5}}}$

$\green{\tt{=\frac{4}{15} + \frac{-2}{5}}}$

$\green{\tt{=\frac{4 + (-6)}{15}}}$

$\green{\tt{=\frac{4 -6}{15}}}$

$\green{\tt{=\frac{2}{15}}}$

$\orange{\bf{ \\ \\Their\:difference }}$

$\red{\tt{=\frac{13}{40} + \frac{2}{15}}}$

$\green{\tt{=\frac{26 + 12 }{80}}}$

$\green{\tt{=\frac{38 }{80}}}$

$\green{\tt{=\frac{\cancel{38} }{\cancel{80}}}}$

$\green{\tt{=\frac{19 }{40}}}$
