(Manual way)

Write it in fraction.
Move the decimal place to the same number in both the numerator and the denominator.
Remove the common factors from both numbers. Here 2 is a common factor.

\frac{1}{0.0182} = \frac{10000}{182} = \frac{5000}{91}

Now, we take the upper approximate and the lower approximate, that is, 100 and 90.

\frac{5000}{100} = 50

\frac{5000}{90} = 55.555555...

So, your answer should be about 1/10th the difference from 55.555, that is 1/10 of 5.555. One tenth of that is 0.555.

So,

\frac{5000}{91} \approx 55

The calculator gives 54.945, which is very close to the approximation :)

I work with college students who don't know what divide and multiply even mean, cause they think they are keys on a calculator. Uh, let's see, we have insurance for one month at $120 - what is that for 3 months, and no clue that it's a multiplication. (And no, I am not exaggerating.)

That is what comes of calculators. One needs to learn manually first!
