Question

verify : a+b =b+a for =3/2,b= 3/5​

Answer 1

Answer:

a+b=b+a

21/10=21/10

Step-by-step explanation:

a=3/2,b=3/5

a+b=b+a

3/2+3/5=3/5+3/2

15+6/10=6+15/10

21/10=21/10

a+b=b+a

hence proved

Answer 2

Step-by-step explanation:

Given

$(a + b) = (b + a)$

and

$\red{a} = \frac{3}{2} \\ \\ \red{b} = \frac{3}{5}$

( a + b ) = ( b + a )

$\blue{( \frac{3}{2} ) + ( \frac{3}{5} )} = \blue{( \frac{3}{5} + ( \frac{3}{2} )}$

( a + b ) :-

$\frac{(3 \times 5)}{(2 \times 5)} + \frac{(3 \times 2)}{(5 \times 2)}$

$\frac{15}{10} + \frac{6}{10}$

$\frac{(15 + 6)}{10}$

$(a + b) ===> \frac{21}{10}$

(b + a) :-

$\frac{(3 \times 2)}{(5 \times 2)} + \frac{(3 \times 5)}{(2 \times 5)}$

$\frac{6}{10} + \frac{15}{10}$

$\frac{(6 + 15)}{10}$

$(b + a) ===> \frac{21}{10}$

:. a + b = b + a

→

$\frac{21}{10} = \frac{21}{10}$

Hence, verified ✔
