Answer:
Hence, the required answer = 17/140
Step-by-step 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
Answer:-
Hence, the required answer = 17/140 .
I hope it's help you...☺
