How are equivalent fractions used when subtracting unlike fractions?
First you find a common multiple of the denominators. The least common denominator is handy but not essential. This number will be the denominator of the answer - before simplification.For both fractions find an equivalent fraction whose denominator is this common denominator.Carry out the subtraction on the new numerators to give the numerator of the answer.Simplify the result for the final, simplified answer.First you find a common multiple of the denominators.

What is an common multiple of the denominators for two or more fractions?
Multiplying the denominators together of two or more unlike fractions will get you a common multiple.
What is the least common denominator of two fractions?
The least common denominator is the least common multiple of the denominators of the fractions.
What is the LCD for fractions?
The LCD for fractions is the LCM (least common multiple) of all of the denominators.

What is the smallest common multiples is called?
It is usually called the least common multiple. But it can also be called the least/lowest common denominator when it is used for addition or subtraction of rational fractions.
The smallest number that can be divided by two or more different denominators is called?
The smallest number that can be divided by two or more different denominators is called the least common multiple (LCM). The LCM of a set of numbers is the smallest multiple that all the numbers share. It is often used in problems involving fractions, where finding a common denominator is necessary for addition or subtraction.
How can knowing the greatest common factor and least common multiple help you when you add subtract and multiply fractions?
Knowing the least common multiple of the denominators will help you find a common denominator when adding and subtracting unlike fractions. Knowing the greatest common factor of the numerator and the denominator will help you reduce the fraction if possible.
What strategies can I use to add and subtract fractions and decimals?
To add and subtract fractions, first ensure they have a common denominator by finding the least common multiple (LCM) of the denominators. Once the fractions have the same denominator, you can add or subtract the numerators while keeping the denominator unchanged. For decimals, align the numbers by their decimal points, and then perform the addition or subtraction as you would with whole numbers. Lastly, ensure to simplify the result if necessary, especially for fractions.
What to do when the denamintor is different numbers?
I am assuming that denamintor is your way of spelling denominator. If not, please explain what it means and we can try to answer your question.The answer depends on what you wish to do. For multiplication or division it does not matter. For addition or subtraction you will need to find the least common multiple and rename the fractions so that their denominators are the same.
How do you know when to subtract fractions or to multiple?
Generally speaking, if the question is about taking something away it is subtraction. If it is about a number of lots or copies or sets of something, it is multiplication.
What makes the least common denominator the most efficient common denominator in addition o subtraction?
It is the lowest common multiple of the different denominators.
How do you get fractions to have the same denominator?
To get fractions to have the same denominator, first identify the least common multiple (LCM) of the denominators. Then, convert each fraction by multiplying both its numerator and denominator by the necessary factor to reach the LCM. This will create equivalent fractions that share the same denominator, allowing for easy addition or subtraction. For example, to add 1/4 and 1/6, you would convert them to 3/12 and 2/12, respectively, giving them a common denominator of 12.
What is the use of number line?
It shows multiple numbers in order to use in addition, subtraction, etc.
Adding unlike fractions?
If the denominators are not the same, then you have to use equivalent fractions which do have a common denominator . To do this, you need to find the least common multiple (LCM) of the two denominators. To add fractions with unlike denominators, rename the fractions with a common denominator. Then add and simplify.
When solving inequalities with multiple operations addition and subtraction are undone before multiplication and division?
Your question is a little confusing. If you are asking which gets done first ... addition/subtraction or multiplication/division ... the multiplication/division is done first. In other words, in 1 + 4 / 2, you divide 4 by 2 first, then add 1. So the answer is 3.
