why does the denominator get larger in a fraction and the decimal get smaller?

    The question is why does the denominator get larger in a fraction then the decimal number gets smaller. First a fraction means divide, so for example 1/8 means 1 divided by 8. So you would get a decimal, but why does the number get smaller? This happens because divide means you make it smaller or it means you put them into groups. What that means is that you put them into groups and make that big group smaller.
    I learned that the reason this happens is because you divide and it makes the fraction into a decimal.
