evaluate : -18 /16 -11/20 -(-13/12)इवोल्यूट - एटीन ओपन 16 - 11 apon 20 - ब्रैकेट - 3 अपॉन ट्वेल ब्रैकेट क्लोज ​

Answer 1

Answer:

Step-by-step explanation:

given

=$\frac{-18}{16}-\frac{11}{20}-(\frac{-13}{12})$

solving bracket, minus, and minus get multiplied

=$\frac{-18}{16}-\frac{11}{20}+\frac{13}{12}$

taking L.C.M. of denominators (16,20,12)=240

solving

=$\frac{-18X15}{16X15}-\frac{11X12}{20X12}+\frac{13X20}{12X20}$

$=\frac{-270}{240}-\frac{132}{240}+\frac{260}{240}$

now solving Numerators

=$\frac{-270-132+260}{240}$

=$\frac{142}{240}$

dividing numerator and denominator by 2 we geet

=$\frac{71}{120}$     answer
