When reducing fractions to their simplest form the greatest common factor of their numerator and denominator must be found.
In calculating fractions.
Adding or subtracting fractions requires the use of a common multiple. It is rare that the LEAST common multiple is required - it is useful to keep the numbers small and manageable.
yes because if there were no fractions there will be nothing.
You are asked to put the fractions on a number line to help you understand fractions. It isn't so much you will use a number line " in real life" but it gives you a visual representation to help you learn. You will use fractions for many things in life. Just do what what you are asked to do by your teacher they have a reason. You are not the only student in the class and others may need a bit extra assignments to help them understand. Go with the flow. Not all things in life will relate to "real life."
Those are commonly used for working with fractions. You need the least common multiple to find a common denominator, for adding or subtracting fractions. And after doing some manipulations with fractions, you need the greatest common factor to simplify the fractions.Now, whether this is sufficiently "real-life" for you, is another issue. Depending on the career you choose, you many need to work with fractions on a daily basis, or you may hardly ever need them.
Number factors help find common denominators in fractions and reducing fractions. In algebra they are used to find the answers to higher level equations like quadratics.

When we simplify fractions.
You use fractions for LOTS of things in the real world like money, gambling, shopping, clothing, etc.

there are None!
How is doing operations (adding, subtracting, multiplying, and dividing) with rational expressions similar to or different from doing operations with fractions?If you know how to do arithmetic with rational numbers you will understand the arithmetic with rational functions! Doing operations (adding, subtracting, multiplying, and dividing) is very similar. When you areadding or subtracting they both require a common denominator. When multiplying or dividing it works the same for instance reducing by factoring. Operations on rational expressions is similar to doing operations on fractions. You have to come up with a common denominator in order to add or subtract. To multiply the numerators and denominators separated. In division you flip the second fraction and multiply. The difference is that rational expressions can have variable letters and powers in them.
