(1) find the LCD. (2) find the factor that each original denominator needs to be multiplied by to get the LCD. (3) multiply both the numerator and the denominator by that factor.
if you go to google.com, you can type in math games and then find a website that has them on it.
you get math help by getting a tutor to help you in math.
Look in your math book you will find the answer!!!
The LCD of 7 and 77 is 77.
In math, the LCD means the Lowest Common Denominator.
LCD means lowest common denominator which is needed when adding or subtracting fractions that have different denominators.
the lcd is the least common denominator but the LCM is the least common multiple.
It means Lowest Common Denominator.
When adding or subtracting fractions with different denominators then their LCD must be found in order to carry out the calculations.
least (or lowest) common denominator
When multiplying fractions, it is not necessary to find the LCD first.
multiples: Least Common Multiple
The least common denominator, or LCD, is the smallest positive integer that all the members of a given set of denominators will divide into evenly with no remainder.
You need at least two numbers to find an LCD.
LCD:Lowest Common Denominator GCF:Greatest Common Factor
The least common denominator, or LCD, is the smallest positive integer that all the members of a given set of denominators will divide into evenly with no remainder.
