Addition and subtraction - what could be easier? But you know that KS3 Maths is anything but easy! In this quiz you'll be adding and subtracting fractions.
Adding and subtracting fractions is not as difficult as it at first appears. All that you have to do is find their lowest common multiple and give both fractions this denominator. You can only add and subtract fractions if they have the same denominator - that's the number below the line. Fractions are made up of two numbers - numerators (the top or first number) and denominators (the bottom or second number). So, to add 2⁄5 and 2⁄3 you need to convert both fractions into 15ths. 2⁄5 = 6⁄15 and 2⁄3 = 10⁄15. 6⁄15 + 10⁄15 = 16⁄15 or 11⁄15. Simple when you know how!
Try the following quiz and you'll soon get the hang of adding and subtracting fractions. Take your time and consider your answers carefully. Good luck!
