Algebra is only going to become more advanced as the years of school pass and if one has not gained full knowledge of it at its most basic level, it will be impossible to venture on. You have to algebra one step at a time. If you do these steps over and over, your brain will start to adjust and you will like it.
Start by following the basic process for fraction multiplication, turning any mixed fractions into improper ones. Before you cross cancel or multiply, however, swap the numerator and the denominator in the second fraction. This is called taking the reciprocal and it is the key step to turn this into a division operation. Then, cross cancel, multiply across to get the answer fraction, and reduce.
When adding fractions without a common denominator, it is necessary to find a common denominator before adding the numerators. Find two equivalent fractions by determining the least common multiple of the two denominators and using that as the denominator for both fractions.
Subtracting fractions is similar to adding fractions. Most of the work involves the denominator. If the denominators of the two fractions are already the same, much of the work is done. Simply subtract the two numerators to get the answer fraction using the same denominator, and then reduce and make a proper fraction.
