Answer :

just do 5550/1000
You get 555/100 simplified
then divide and get 5.55
5.55 is your answer or just 5 11/20
I'm guessing you want a mixed number.

To find this, find out how many times 1000 goes into 5550.
It goes in it evenly 5 times.

Now find what's left over. 
5 x 1000 = 5000
5550 - 5000 = 550

Use 5 as the whole number, 550 as the numerator, and keep the denominator the same, which is 1000.

Now, the fraction in 5 550/1000 can be reduced.
50 goes into both.

550/50 = 11
1000/50 = 20

So  the fraction is reduced to 11/20.

Your fraction is 5 11/20.


Now, if you were looking for a decimal, simply refer to the fraction.
Obviously, the whole number is 5.

To make life easier, multiply 20 to 100.
20 x 5 = 100.

Now we know the numbers to the right of the decimal will have two places.

Multiply 11 to 5.
11 x 5 = 55.

So, .55

Your final answer is 5.55



Fraction: 5 11/20
Decimal: 5.55
