Perform the indicated operations:(i) \left(-\frac{7}{8}+\frac{-5}{12}\right)+\frac{3}{16}(ii) \left(\frac{7}{3}+\frac{3}{4}\right)+\left(-\frac{3}{5}\right)

Answer»

(i) take LCM of 8,12=24[(-7(3)+(-5)(2))/24]+3/16[(-21-10)/24]+3/16-31/24+3/16Take LCM of 24,16=48(-31(2)+3(3))/48(-62+9)/48-53/58

(ii) Take LCM of 3,4=12[(7(4)+3(3))/12]+(-3/5)[(28+9)/12]+(-3/5)37/12-3/5Take LCM of 12,5=60(37(5)-3(12))/60(185-36)/60149/60
