Answer 1

Answer:

Given :

(-3)/5 + (4/7 * 3/5) - 4/9 * ( 2/3 * 1/5 ) - 15/16 + ( 1/5 * 4/3 )

To find :

Simply the problem using suitable properties of rational number .

Solution :

This type of problems can be solved using the rule of BODMAS .

=> (-3)/5 + ( 4/7 * 3/5 ) - 4/9 * ( 2/3 * 1/5 ) - 15/16 + ( 1/5 * 4/3 )

=> (-3)/5 + ( 12/35 ) - 4/9 * ( 2/15 ) - 15/16 + ( 4/15 )

=> (-3)/5 + ( 12/35 ) - 8/135 - 15/16 + ( 4/15 )

=> 64/105 - 3/5 - 8/135 - 15/16

=> 1/105 - 8/135 - 15/16

=> (-47)/945 - 15/16

=> -14927 / 15120

(-3)/5 + ( 4/7 * 3/5 ) - 4/9 * ( 2/3 * 1/5 ) - 15/16 + ( 1/5 * 4/3 ) = (-14927)/15120
