Verify associative property of addition of Rational numbers for = −11/ 10 , = 21/ 5 = −1/2 |
|
Answer» Step-by-step EXPLANATION:Given numbers are -10/11 , 5/6 and 4/3 To Verify the associative property for ADDITION and multiplication of the RATIONAL numbers. Associative Property for addition of the rational numbers is as follows ( a + b ) + C = a + ( b + c ) Associative Property for multiplication of the rational numbers is as follows ( a × b ) × c = a × ( b × c ) let a = -10/11 , b = 5/6 and c = 4/3 So, FIRST Associative property of addition: LHS = ( a + b ) + c = ( -10/11 + 5/6 ) + 4/3 RHS = a + ( b + c ) = -10/11 + ( 5/6 + 4/3 ) LHS = RHS Hence Verified Second, Associative property of multiplication: LHS = ( a × b ) × c = ( -10/11 × 5/6 ) × 4/3 RHS = a × ( b × c ) = -10/11 × ( 5/6 × 4/3 ) LHS = RHS |
