Question

Find the inverse of 2 1 3 / 4 -1 0 / -7 2 1​

Answer 1

Answer:

$one \: number \: \frac{213}{4}$

the other number with sign in between these two numbers

$- ( \frac{10}{ - 721} ) \\ = \frac{10}{721}$

$\frac{213}{4} + \frac{10}{721} \\ \frac{(213) \times 721 + (10)4}{2884}$

$\frac{153573 + 40}{2884} \\ = \frac{153613}{2884} \\ = \frac{5325}{100}$

inverse will be

$\frac{100}{5325}$
