Answer 2

Answer:

Hence , the required answer = 17/140

Explanation:

Rearrangement Property of Addition: The addends in an addition expression may be arranged and grouped in any order. This is a combination of the associative and commutative axioms.

Here its given,

(-13) / 20 + 11 / 14 + (-5) / 7 + 7/10

After rearranging the given equation we get,

{ (-13) / 20 + 7 / 10 } + { 11 / 14 + (-5) / 7 }

=> { (-13 + 14) / 20 } + { (11 - 10) / 14 }

=> 1 / 20 + 1 / 14

Then by taking the LCM of denominators we get,

LCM (14 and 20) = 140

=> 7 / 140 + 10 / 140

=> (7 + 10) / 140

=> 17 / 140

Hence , the required answer = 17/140
