Q.2

Add the following rational numbers:

-7/27 + -5/18

Answer 2

-7/27 +-5/18

first, find the LCM

=54 (18 x 4 and 27 x 2)

now multiply the numerator by the second factors that is -7 x 4 and -5 x 2 and take the LCM, that is 54, as common denominator

= -7x4 + -5 x 2 /54

= (-28)+(-10)/54

= -28-10/54

= -38/54

BY SIMPLIFYING, WE GET -19/27

= -19/27 is the answer!
