Answer 2

Solution.)

The question is - ( 1 / 2 ) - 2 + ( 1 / 3 ) - 2 + ( 1 / 4 ) - 2

= we will solve the first part of the question -

( 1 / 2 ) - 2

= ( 1 / 2 ) - ( 2 / 1 )

= lcm = 2

1 / 2 - 2 * 2 / 2 * 1

1 / 2 - 4 / 2

= -3 / 2

Next , we will solve the second part -

= -3 / 2 + ( 1/3 - 2)

= - 3 / 2 + lcm = 6 ( 1 * 2 / 3 * 2 - 2 * 6 / 1 * 6 )

= - 3 / 2 + 2 / 6 - 12 / 6

= -3 / 2 + -10 / 6

= lcm = 6 , -3 * 3 / 2 * 3 + -10 / 6

= -9 / 6 + -10 / 6

= - 19 / 6

= - 19 / 6 + ( 1 / 4 + 2 )

= -19 / 6 + lcm = 4, 1 / 4 - 2 * 4 / 1 * 4

= -19 / 6 + - 7 / 4

= lcm = 24

= - 19 * 4 / 6 * 4 + -7 * 6 + 4 * 6

= - 76 / 24 + -42 / 24

= -76 + -42 / 24

= - 118 / 24

= bring it to lowest form =

= -59 / 12

= 11
