Question

4/16+(-6/13)+(-7/8)+21/26 using commutative and associative property

Answer 1

To Solve :

4/16+(-6/13)+(-7/8)+21/26 using commutative and associative property.

Solution :

Commutative property

a+b = b+a

Associate property

a + ( b+c) = ( a + b ) + c

4/16+(-6/13)+(-7/8)+21/26

•Firstly we'll arrange them using commutative property which tells that addition of rational no. is free of order

4/16+(-7/8)+21/26+(-6/13) =

( 4/16 -7/8 ) + ( 21/26 - 6/13 )

Using LCM to make the denominators same

= (4 - 14)/16 + (21-12)/26

= -10/16 + 9/26

Again making the denominators same

= -140/208 + 72/208

= -68/208

= -17/52

• Hence

4/16+(-6/13)+(-7/8)+21/26 = -17/52
