To determine the fraction between these two values you have to do as follows:
Divide them
[tex]\frac{1200}{2000}[/tex]First step of the simplification is to cancle or "take away" the last two zeros of the numerator and denominator:
[tex]\frac{1200}{2000}=\frac{12}{20}[/tex]Both expressions are equivalent and give the same result.
Now you have to simplify the fraction by choosing a common factor between both values.
Factors of 12:
1, 2, 3, 4, 6, 12
Factors of 20
1, 2, 4, 5, 10, 20
The Commonf factors between these two values is 4.
Divide the numberator and denominator of the fraction by 4:
[tex]\frac{12\div4}{20\div4}=\frac{3}{5}[/tex]The fraction of 1200 of 2000 is
[tex]\frac{3}{5}[/tex]
