Numerator / Denominator
Numerator: We call the top number the Numerator, it is the number at the top of the fraction you have.
Denominator: We call the bottom number the Denominator, it is the whole number that is at the bottom, it is the number that is divided into.
Fraction to decimal conversion steps
Step 1: Find a number you can multiply by the bottom of the fraction to make it 10, or 100, or 1000, or any 1 followed by 0s.
Step 2: Multiply both the top and bottom by that number you choose.
Step 3. Then write down just the top number, putting the decimal point in the correct spot, that is one space from the right hand side for every zero in the bottom number.
