you have to write down the fraction example if is 9 over 18... 9/18, we cannot help you without knowing the fraction.... but you can divide the numerator by the denominator using long division... for mine example of 9/18 would be 9 divided by 18, which would be 0.5 as a decimal.
top number = numerator
bottom number= denominator
numerator ÷ denominator = decimal
