Question

Verify That a + (b + c) = (a + b) + c by taking a = 1/2 , b = 3/4 , c = -2/3​

Answer 1

Answer:

proved

Step-by-step explanation:

given a=1/2 b = 3/4 c=-2/3

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

$\frac{1}{2} + ( \frac{3}{4} - \frac{2}{3} ) = ( \frac{1}{2} + \frac{3}{4} ) - \frac{2}{3} \\ \frac{1}{2} + ( \frac{9 - 8}{12} ) = ( \frac{2 + 3}{4} ) - \frac{2}{3} \\ \frac{1}{2} + \frac{1}{12} = \frac{5}{4} - \frac{2}{3} \\ \frac{6 + 1}{12} = \frac{15 - 8}{12 } \\ \frac{7}{12} = \frac{7}{12}$

i hope this will be the answer

Answer 2

Answer:

a = 1/2

b = 3/4

c = -2/3

a + ( b + c ) = 1/2 + { 3/4 + ( -2/3)}

= 1/2 + ( 3/4 - 2/3 )

= 1/2 + 1/12

= 7/12

( a + b ) + c = ( 1/2 + 3/4 ) + ( - 2/3 )

= 5/4 - 2/3

= 7/12

Hence Verified ..
