Well if you had 4 ounces of vanilla and the total milkshake was 12 then 12 would become the denominator and the 4 is what part of the milkshake is so 4 is the numerator and that would make it 4/12 and then you can simplify 4/12 and it would = 2/6
The total amount is 12 ounces therefore you can use that as your denominator. 4 ounces out of it are vanilla and the other 8 are chocolate. 4 out of 12 is vanilla . This can also be written as 4/12. 4/12 can be your first fraction. The second one can be a simplified version of 4/12. The simplified version would be 1/3. Your two fractions would be 4/12 and 1/3.
