Question

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

Answer 1

HEY MATE !!!

$(\frac{4}{15} + \frac{2}{ - 5} ) - ( \frac{ - 3}{10} + \frac{5}{8} )$

$( \frac{4}{15} - \frac{2}{5} ) - ( \frac{ - 3}{10} + \frac{5}{8} )$

Taking LCM in both the brackets

$( \frac{4}{15} - \frac{6}{15} ) - ( \frac{ - 12}{40} + \frac{25}{40} )$

$( \frac{4 - 6}{15} ) - ( \frac{ - 12 + 25}{40} )$

$( \frac{ - 2}{15} ) - ( \frac{13}{40} )$

$\frac{ - 2}{15} - \frac{13}{40}$

taking LCM

$\frac{ - 16}{120} - \frac{39}{120}$

$\frac{ - 55}{120} = \frac{ - 11}{24}$
