Question

from the sum of - 8/7 and - 11/4,subract the difference of 1/9 and - 12/3​

Answer 1

Answer:

$sum \: of \: \frac{ - 8}{7} and \frac{ - 11}{4} = \frac{ - 8}{7} + \frac{ - 11}{4} \\ lcm \: of \: denominators = 28 \\ = > \frac{ - 8}{7} + \frac{ - 11}{4} = \frac{ - 32 - 77 }{28} \\ = \frac{ - 109}{28} \\ difference \: of \: \frac{1}{9} and \frac{ - 12}{3} \\ = \frac{1}{9} - \frac{ - 12}{3} = \frac{1}{9} + \frac{12}{3} \\ lcm \: of \: denominators = 9 \\ = > \frac{1}{9} + \frac{12}{3} = \frac{1 + 36}{9} = \frac{37}{9}$

=> (-109/28)-(37/9)

LCM of denominators = 9×28=252

=>(-109/28)-(37/9)=(-981-1036)/252

=(-2017/252)
