Common misconception
Children may make mistakes when using the generalisation if they are unaware of the structure behind it and the reason that we multiply then add.
First multiply the whole number by the denominator then add the numerator. Multiplying the whole number by the denominator tells us the number of parts that can be made from the whole number part then we need to add the parts shown by the numerator.
