How do you convert 0.55 to a fraction in its simplest form?

11/20

Explanation:

0.05 = 1/20.

This is because 20 xx 0.05 = 1.00

Now:

0.05 xx 11 = 0.55, which means that

0.55 = 11/20

11/20

Explanation:

Before we get to simplifying, let's just go ahead and convert this decimal into a fraction. We know that 0.55, by definition, means 55 " hundredths " This can simply be written as:

55/100

Now that we have a fraction, simplification is much (wait for it) simpler. The biggest part of simplification involves finding a common factor between the numerator and denominator of the fraction. You may have heard of this as the Greatest Common Factor, or GCF.

In this case, notice that both 55 and 100 are divisible by 5. Hence, let's go ahead and divide each term by 5:

(55 -: 5)/(100div5) = 11/20

This leaves us with

11/20

Since 11 and 20 do not share any common factors (apart from 1), we can conclusively say that this is the most simplified we can get.

So, there you are. Your answer is 11/20.

Hope that helps :)

Simplify top and bottom by the highest common factor (5)

(55 div 5)/(100div 5) = 11/20
