Question

The multiplicative inverse of 0.8 is:-

Answer 1

Answer:

5 by 4

Step-by-step explanation:

Converting 0.8 in fraction is equal to 8 by 10

Now doing reciprocal of 8 by 10 is equal to 10 by 8..now it's divisible by 2...so now answer is 5 by 4

Answer 2

let the given value be 'x'

$x = 0.8\\ \\x = \frac{8}{10}\\\\x = \frac{4}{5}$

Now, multiplicative inverse is a number when multiplied with its original value gives result as 'one'.

Therefore,

$x*\frac{5}{4} = \frac{4}{5}* \frac{5}{4} \\\\x*\frac{5}{4}= 1$

By multiplying 'x' with $\frac{5}{4}$ we get the result as 'one'

∴Multiplicative inverse of $0.8$ is $\frac{5}{4} = 1.25$
