What is 2.16 converted to a fraction?

Answer 1

To convert a number to a fraction, the easiest way is to first multiply a number by a power of ten such that there are no decimal numbers left. In this case, we can multiply by 100 to get 216. The 100 we multiplied by becomes the denominator, so the starting point is 216/100. The next step is to identify any common factors. In this case, both numerator and denominator can divide by 4, so do this and we get 54/25. This is the fraction in its simplest form, although it is a vulgar fraction. To convert it into a mixed number we take the units out and repeat the process above to end up at 2 and 4/25
