Answer 1

Answer:

heya mate ☺

☆ So 76 / 120 should be added with - 13 / 20

☞ Verification of my answer :

$\frac{76}{120} + ( \frac{ - 13}{20} ) \\ \\ = \frac{76}{120} - \frac{13}{20} \\ \\ = \frac{76 - 78}{120} \\ \\ = \frac{ - 2}{120} \\ \\ = \frac{ - 1}{60}$

♡ hope it helps u mate ♡

Answer 2

Answer:

$let \: x \: be \: added \: to \: \frac{ - 13}{20} \\ \\ so \: according \: to \: the \: question \\ \\ \frac{ - 13}{20} + x = \frac{ - 1}{60} \\ \\ = > \frac{ - 13 + 20x}{20} = \frac{ - 1}{60} \\ \\ = > 60( - 13 + 20x) = - 20 \\ \\ = > - 780 + 120x = - 20 \\ \\ = > 120x = - 20 + 780 \\ \\ = > 120x = 760 \\ \\ = > x = \frac{760}{120} \\ \\ = > x = \frac{76}{12}$
