Question

What is 9.1 divided by 3576 and than the answer rounded to the nearest whole number?

Answer 1

9.1 is less than half of 3576, so it's going to round down to 0. (mental math)

I'm not sure if you were also asking for the actual value because of the wording, so here it is if you need it.

As a fraction, $\frac{9.1}{3576}=\frac{91}{35760}$.
(multiply both the top and the bottom by 10)

As for the actual decimal value, it's something like 0.0025447....You can find this out using long division (you're going to have to know the multiples up to 10 of 3576, so list those off to the side) or simply a calculator. As for handling the decimal, just divide into the 9.1 like a normal number (only the digits are important when you're doing the long division) and bring up the decimal point when you're done. You might also need to use zeroes as placeholders. (9.1 = 9.10000...)
