You were correct

Here's Why

So when turning decimals into fractions you have to look at the decimal point and moves as many points to the right as you need. So in this case, you would move it 2 times to the right indicating 2 0's at the end of 1 so move it to the right 3 times it would be 45/1000 and so on and so on. Hope this helps!

step-by-step explanation:

the multiplicative inverse of a fraction a/b is b/a. for the multiplicative inverse of a real number, divide 1 by the number. for example, the reciprocal of 5 is one fifth 1/5 or 0.2, and the reciprocal of 0.25 is 1 divided by 0.25, or 4.

0.84 dang lotta people are looking for this lol or if you round up its 1 but the overall answer to that is 0.84
