Question

if a= 1/2 b= 1/3 verify the following
a×b= b×a
a+b=b+a
​

Answer 1

Answer:

Step-by-step explanation:

we know

a=1/2   and    b=1/3

now

a×b=b×a

1/2×1/3 = 1/3×1/2

1/6 = 1/6

∴ proved

a+b = b+a

1/2+1/3 = 1/3+1/2

5/6 = 5/6

∴proved

Answer 2

Answer:

$1. \: a \times b = b \times a \\ \frac{1}{2} \times \frac{1}{3} = \frac{1}{3} \times \frac{1}{2} \\ \frac{1}{6} = \frac{1}{6} \\ 2. \: a + b = b + a \\ \frac{1}{2} + \frac{1}{3} = \frac{1}{3} + \frac{1}{2} \\ \: LCM \: of \: 2 \: and \: 3 \: is \: 6 \\ \frac{3}{6} + \frac{2}{6} = \frac{2}{6} + \frac{3}{6} \\ \frac{ 5}{6} = \frac{5}{6}$
