Comparing and orderingHow to convert fractions to decimalsTo convert a fraction to a decimal , you have to divide the numerator (top number) by the denominator (bottom number) , this means the top number goes under the division symbol and the bottom number goes outside the division symbol.
Example - the 3 is the numerator (top number) and the 4 is the denominator (bottom number)How to convert fractions to decimals continued
