Reducing fractions
Very few. Since the least common factor of every set of positive integers is 1, it doesn't really provide you with helpful information.
Finding the GCF will help in simplifying fractions. Finding the LCM will help in adding and subtracting fractions.
The three possible types of modification problems are: Deletion, update, and insertion problems

There is no single method to solve all types of fraction problems. Some problems and their solutions are relatively simple, others are extremely difficult.
Blood
There are lots of different types of problems in algebra; you have to learn each type separately. For example, how to add similar expressions; how to multiply expressions; how to factor polynomials; how to solve equations; etc.
Rh-factor (or D for Duffy) protein is divided among races. Fifteen percent of whites are Rh negative, 5 to 10 percent of African Americans are Rh negative, and 1 to 2 percent of Asians are negative for the protein. One percent of humans are type AB. It takes a little study to understand blood types and you should work a few problems to understand how they work. But it isn't very hard to do. See the links below to see how this works:
