With dissimilar fractions you should memorize and again really memorize that 1/2 + 1/4 should equal 3/4. So during the exam whatever solution you used to come up with 3/4 then you should use the
same to add dissimilar fraction. Again this is just a reminder in case you forget a bit. For example if you do not come up with 3/4 as the answer, that would only mean that you should not go on adding dissimilar fractions because you had already forgotten on how to solve it, then you can just concentrate on answering questions that you can answer.

With Multiplying fractions you should memorize that 1/2 x 1/2 should equal 1/4 (numerators 1 x 1 = 1 and denominators 2 x 2 = 4. Again doing this is like a trial and error
