Question

Find 3/7+(-6/11)+(-8/12)+(5/22)

Answer 1

Solution :-

3/7 + (- 6/11) + (- 8/21) + (5/22)

Taking L.C.M. of the denominators 7, 11, 21 and 22 and then solving it.

L.C.M. of 7, 11, 21 and 22 = 2*3*7*11

= 462

= (462/7)*3 - (462/11)*6 - (462/21)*8 + (462/22)*5

= (198/462) - (252/462) - (176/462) + (105/462)

= (303/462) - (428/462)

= (-125/462)

Answer 2

Answer:

−0.5108225103939

Step-by-step explanation:

By using BODMASS

3/7=0.428571429

-6/11=0.545454545

-8/12=0.666666667

5/22=0.227272727

0.428571429 - 0.545454545 - 0.666666667 + 0.22727272 = −0.5108225103939 or -0.511.
