To convert 2.125 to a mixed number, first identify the whole number part, which is 2. The decimal part, .125, can be written as a fraction by placing it over 1000 (since there are three decimal places). So, .125 can be written as 125/1000. Simplify this fraction to 1/8. Therefore, 2.125 as a mixed number is 2 1/8.

There's no fun in playing it safe. Why not try something a little unhinged?

take the decimal part and put it over 1, so you would get 0.125/1. Now you want to get a 1 in the numerator (top number in a fraction), so divide 0.125 by itself. To keep things equivalent you would have to divide the denominator (bottom number in a fraction ) by 0.125 as well. So you get 0.125/1 / 0.125/0.125 = 1/8. So this number is basically 2 1/8. The more you do this, the more you will start to recognize the fractional equivalents to different decimals. For instance, I alread knew that 0.125 was 1/8 - it just comes with practice.
