Answer 2

Answer:

( a ) 1 / 6   ( b ) 3 / 10    ( c ) 1 / 4

Step-by-step explanation:

For addition, subtraction, comparison of fractions, take their LCMs and convert

( a ) 1 / 8 + 1 / 24

     LCM of 8 , 24 = 24

     ( 1 * 3 / 8 * 3 ) + ( 1 * 1 / 24 * 1 )

     3 / 24 + 1 / 24  =  ( 3 + 1 ) / 24  =  4 / 24 ( or ) 1 / 6

( b ) 1 / 4 + 1 / 20

     LCM of 4 , 20 = 20

     ( 1 * 5 / 4 * 5 ) + ( 1 * 1 / 20 * 1 )

     5 / 20 + 1 / 20  =  ( 5 + 1 ) / 20  =  6 / 20 ( or ) 3 / 10

   

( c ) 1 / 6 + 1 / 12

     LCM of 6 , 12 = 12

     ( 1 * 2 / 6 * 2 ) + ( 1 * 1 / 12 * 1 )

     2 / 12 + 1 / 12   =  ( 2 + 1 ) / 12   =  3 / 12 ( or ) 1 / 4
