Divide both numbers by 5.

Look for a common factor and just cancel down. It is obvious that 5 goes into both 10 and 55 (Remember that multiples of 5 all end in 5 or 0)
So how many 5s in 10? 2
how many 5s in 55?
11

that leaves you with

The general method for problems like this is factorise the top and bottom, and eliminate any factors which appear on top and bottom.

So 10=2x5, 55=5x11, and (2x5)/(5x11) simplifies to 2/11

10/5 = 2

55/5 = 11

Therefore 10/55 == 2/11

To simplify such fractions, you find a common factor for each side and divide by it. It is very important that what you do to the numerator (above the slash), you also apply the same to the denominator (below the slash).

Example:

24/36

You notice they are even numbers, so one common method can be to halve it (divide by 2) = 12/18

Notice that you can still simplify it even further. Halve it again = 6/9

You'll find that both numbers can be divided by 3, therefore: 2/3

You can simplify fractions using these small steps, or the more faster way is to find the highest common factor. For instance, both 24 and 36 can be divided by 6. Therefore: 4/6, and if you half this, you get 2/3, same result as above, but less steps.
