If the two values being subtracted are mixed fractions, it is often easier to turn them into improper fractions to perform the subtraction. This avoids any kind regrouping or borrowing from the minuend fraction if the numerator in the subtrahend is larger.
One of the first skills students learn is addition. Addition is the natural advance after counting. Many students do not grasp this basic skill properly. As a result, students find it difficult to advance to higher level skills and they get stuck. Therefore, to make the task easier, here are five easy ways to learn addition. You may have heard of some of these games, they go by many different names. In addition to some simple games, we offer up some techniques to keep in mind when adding numbers in general. If you are already good at addition, you will still find these tips helpful to make you faster at addition.
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.
Long Division. There are different methods for dividing multi-digit numbers (long division). One way is a combination of estimation/ trial and error and multiplication. There is also a commonly used algorithmic method that is well explained and illustrated here at mathisfun.com.
