To subtract two rational expressions that have a common denominator You simply?
You subtract the numerators, and place it over the common denominator.
What do you subtract when you have two rational expressions that have a common denominator?
When subtracting you have to make sure that the second numerator is multiplied by -1 so the equation turns into adding. When you add and you already have a common denominator you add the numerators and leave the denominator the same.
How is doing operations with rational expressions similar or different from doing equations with fractions and how can they be used in real life?
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.
After you add or subtract two rational expressions the next step is to put your answer in form?
reduced form $ara ;)
What is the difference between adding and subtracting fractions?
to add a fraction, get a common denominator, then add the numerators. example: 2/10+4/5 first get common denominators 2/10+8/10 then add the numerators 10/10 (simplify) 1 to subtract from a fraction, get common denominator, then subtract the numerators. example: 4/5-2/10 first get common denominators 8/10-2/10 then subtract the numerators 6/10 (simplify) 3/5

To subtract two rational expressions that have a common denominator you simply the numerators?
Yes, eg 13/17 - 4/17 = 9/17

What is the process of subtracting fractions?
If the denominators are the same, subtract the numerators. If the denominators are different, convert them to equivalent fractions with a common denominator and subtract the numerators.
What is a subtracting mixed number?
Subtracting a mixed number is just subtracting fractions but with a whole number by a fraction. To subtract tun the mixed numbers into improper fractions and find the common denominator. Then you subtract the numerators.
How is subtracting decimals is like subtracting fractions?
because you subtract the 2 numerators and then 2 denominators right across just like that :)
What are the rules in subtracting similar fraction?
If the denominators are the same (which is what I understand by "similar fractions"), just subtract the numerators (the upper part).
How do you minnous fractions?
Subtracting fractions is similar to adding fractions. If the fractions have the same denominator, you subtract the numerators. If the fractions have different denominators, you have to convert to a common denominator first.Subtracting fractions is similar to adding fractions.

How do you subtract mixed fractions when they have the same denominator?
The numerator of the answer is the result of subtracting the numerators of the fractions, and the denominator of the fraction is the same as the common denominator.
After you add or subtract two rational expressions it's a good idea to see if you can your answer?
reduce
How do you borrow when subtracting a fraction?
If you have common denominators, then you subtract the numerators of the fraction in the same way you do any other numbers. So yes you can borrow.
