Question

b) If a, b, c are three rational numbers where a = , b = and ca Verify: a + (b + c) = (a + b) + C​

Answer 1

Answer:

a+b+c =a+b+c

take a=$\frac{1}{2}$ , b=$\frac{-3}{4}$ , c=$\frac{3}{10}$

$\frac{1}{2} +\frac{-3}{4} +\frac{3}{10} = \frac{1}{2} +\frac{-3}{4} +\frac{3}{10}$

$\frac{1}{20} =\frac{1}{20}$

Both are equal

Step-by-step explanation:

given

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

a,b and c are rational numbers...

take a=$\frac{1}{2}$ , b=$\frac{-3}{4}$ , c=$\frac{3}{10}$

$\frac{1}{2} +(\frac{-3}{4} +\frac{3}{10}) = (\frac{1}{2} +\frac{-3}{4}) +\frac{3}{10}$

$\frac{1}{20} =\frac{1}{20}$
