Question

simplify and write in the form of p by q minus 2 by 3 minus 5 by 6 plus minus 7 by 24 - (- 13 by - 36)​

Answer 1

Answer:

$= ( \frac{ - 2}{3} ) - ( \frac{5}{6} ) + ( \frac{ - 7}{24} )- ( \frac{ - 13}{ - 36} ) \\ \\ = (\frac{ - 12 - 15}{18} ) - ( \frac{7}{24} - \frac{13}{36} ) \\ \\ = (\frac{ - 27}{18} ) - ( \frac{252 - 312}{864} ) \\ \\ = ( \frac{ - 3}{2} ) - ( \frac{ - 60}{864} ) \\ \\ = ( \frac{ - 3}{2} ) + ( \frac{15}{216} ) \\ \\ = \frac{ -648 + 30}{432} \\ \\ = \frac{ - 618}{432} \\ \\ = \frac{103}{72} \\ \\ = \frac{p}{q}$
