Question

Check whether a÷ b = b÷a where a= 5/2 , b= 15/8​

Answer 1

a = 5/2

b = 15/8

a ÷ b = 5/2 ÷ 15/8

        = 5/2 × 8/15

        = 4/3

b ÷ a = 15/8 ÷ 5/2

        = 15/8 × 2/5

        = 3/4

∴ Both are not equal

Answer 2

Answer:

Calculating LHS

$= > a \div b \\ = > \frac{5}{2} \times \frac{8}{15} = > \frac{4}{3} ........................(1)$

Now Calculating RHS,

$= > b \div a \\ = > \frac{15}{8} \times \frac{2}{5} = > \frac{3}{4} ........................(2)$

Now by Equations 1 and 2,

$\frac{a}{b} \: is \:not \: equal \: to \: \frac{b}{a}$

Hence proved.......
