How can knowing the GCF and LCM help you when you add subtract and multiply fraction?
Knowing the LCM of the denominators of unlike fractions will help you find the least common denominator, a necessary step in adding and subtracting them. Knowing the GCF of a numerator and denominator will tell you if the fraction can be reduced.
Why does the fraction that results from adding or subtracting fractions with unlike denominators have a different denominator?
When you add fractions that have unlike denominators, the first step is to convert them so they are expressed as fractions using the least common denominator. The result is that the answer will have a different denominator, or it may use one of the original two denominators.For example if you are adding 1/10 and 3/5, the least common denominator is 10, the problem is rewritten as 1/10 + 6/10 = 7/10But if you are adding 1/5 and 1/6, the least common denominator is 30 and the problem is rewritten as 6/30 + 5/30 = 11/30
What is the second step of finding LCM?
If the first step is writing down the numbers, the second step is finding their prime factorizations.
What are the steps to multiplying rational numbers?
Step 1 Make the whole number a fraction by making it ?/1 Step 2 Make the mixed number a improper fraction by multiplying the denominator by the whole number and then adding the numerator and putting that on top of the original denominator. Step 3 SOLVE using basic multiplying fractions rules Step 4 SIMPLIFY

What is the first step when adding decimals?

What are the step in subtracting disimilar fraction?
Same as for adding: If the denominators are not equal, you must first find a common denominator, then convert both fractions to that common denominator.

Where does the name completing the square come from?
The first step, in solving a quadratic equation in a variable x using this method, is to complete the square defined by the terms in x2 and x, by adding and subtracting a suitable constant.
When adding or subtracting two fractions with denominators that are not equal what is the first step you take?
The first step to take is find the lowest common denominator of the fractions which can be done by finding the lowest common multiple of the numbers.
When adding two fractions with unlike denominator's which of these steps is the first step?
The first step is to make the denominators the same.
What are the step in adding disimilar fraction?
The first step is to find the lowest common denominator of the fractions.
What is the meaning of 2 step equation?
two algebraic steps (not counting simplification steps) must be used to solve the problem. 1st step is adding or subtracting some quantity from both sides of the equation. 2nd step is multiplying or dividing by a number to solve.
How do you solve 3 step equations with parentheses?

What is the first step when you add rational numbers with decimals?
You write them, one below the other, with their decimal points aligned.
How do subtract fractions?
all you have to do is follow the same algorithm for adding a pair of fractions together. the main step is to find common denominators between the two. to do this, you need to find the least common multiple. another way you could find a common denominator is just by changing them into decimals, and adding them normally like whole numbers with the decimals lined up correctly.
