What is the common denononator?
In fractions, the denominator is the bottom number. When adding or subtracting fractions, it is helpful if all the denominators are the same. To do this, we look for common denominators, which is the same process as finding the least common multiple.
How can you solve a multistep problem that involves fraction?
The first step is to find the least common multiple (LCM) of all the denominators. Next, multiply each term by this LCM. When you have done this you will have a multistep problem which is free of fractions.
What is the smallest number that can be divided by two or more different denominator is called?
The smallest number that can be divided by two or more different denominators is the "least common multiple" or LCM of those numbers.
What is the LCD for fractions?
The LCD for fractions is the LCM (least common multiple) of all of the denominators.
Would you change all of the denominators into a 12 for a fraction model?
Of course not! If the question was about 1/5+2/5 changing the denominators to 12 would make no sense at all! The denominators need to be changed to their lowest common multiple.
What must you find in order to add or subtract unlike fractions?
A common denominator. The best way is to find the LCM (Lowest Common Multiple) of all the denominators - the smallest number into which all the denominators will divide. (The easiest way to do this is to multiply all the different denominators together. Once this common denominator has been found, convert all the fractions into equivalent fractions with this new denominator.
How do you add three fractions with unlike denominators?
-- Find a common denominator. (It will be a number of which all three denominators are factors. The best choice is their least common multiple.) -- Change the fractions to their equivalents with the common denominator. -- Then add their numerators to get the numerator of their sum.
How do solve a least common multiple problem?
you list all the multiples of each number until you come to the first number that is in all columns
How do you simplify an algebraic expression that has fractions?
Multiply every term in the expression by the least common multiple of all the denominators. That will get rid of all fractions.
What is the common denominators for 735 1125?
The lowest common denominator (or multiple) for 735 and 1125 is 55125. All other common denominators for 735 and 1125 are multiples of 55125, namely 110250, 165375, 220500, etc.
What is a greatest common multiple?
There is no such number. The LEAST COMMON MULTIPLE (LCM) is the smallest number that is a multiple of both numbers (or all numbers in a set). It is used to make common denominators. The GREATEST COMMON FACTOR (GCF) is the largest number that is a factor of both numbers (or all numbers in a set). It is used to reduce fractions to simplest form.
The product of a given number and another whole number?
All that can be said is that it is a multiple of the first number.
