Question

using properties of rational numbers evaluate 5/7+2/11+-8/7+6/11 give full solution ​

Answer 1

Answer:

5/7 + 2/11 - 8/7 + 6/11

Step-by-step explanation:

Grouping fractions with same denominators,

Therefore, 5/7 - 8/7 + 2/11 + 6/11

= 1/7(5-8) + 1/11(2+6)

= 1/7(-3) + 1/11(8)

= -3/7 + 8/11

= -3/7(11/11) + 8/11(7/7)

= -33/77 + 56/77.....[L.C.M. = 77]

= 1/77(-33+56)

= 23/77
