Problem sums with different fractions in the same question.
Many students will simply start doing fraction subtraction by making the denominator to the a common multiple of the 3 denominators.
But that will result in a wrong answer as not all fractions are representing the same total.
Eg. 1/4 kg of the rice is not the same as 1/4 of the rice.
1/4 kg of rice represents 1/4 of a kilogram of rice
but
1/4 of rice represents 1/4 of the total of all the rice.
Such questions usually appear in Paper 1.
