What problems can be solved using gcf and LCM?
Finding the LCM will make adding and subtracting fractions easier.
What types of problems can be solved using the the LCM?
Anything having to do with adding or subtracting unlike fractions.
IS THE LCD OF TWO FRACTIONS THE SAME AS THE LCM NUMERATORS AND FRACTIONS?
The LCD of two fractions is the same as the LCM of their denominators.
What types of problems can be solved using the greatest common factor and what types of problems can be solved using the least common multiple.?
Finding the GCF will help in simplifying fractions. Finding the LCM will help in adding and subtracting fractions.
Why would you want to rename fractions with the LCD?
Possible reasons: To add or subtract fractions, To compare fractions with different denominators.
When adding fractions with unlike denominators it is most helpful if the fractions are renamed using the?
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.
What problems can be solved using gcf and LCM?
Finding the LCM will make adding and subtracting fractions easier.
What does find the common denominator for the fraction pairs mean?
It means find the LCM of the denominators. In order to add and subtract fractions with unlike denominators, it is necessary to convert them to equivalent fractions with a common denominator. Example: 1/4 + 1/6 The LCM of 4 and 6 is 12. 1/4 = 3/12 1/6 = 2/12

IS THE LCD OF TWO FRACTIONS THE SAME AS THE LCM NUMERATORS AND FRACTIONS?
The LCD of two fractions is the same as the LCM of their denominators.
What is the LCM for 3.14 and 1.7 in fractions?
The LCM refers to integers, not fractions.
What types of problems can be solved using the greatest common factor and what types of problems can be solved using the least common multiple.?
Finding the GCF will help in simplifying fractions. Finding the LCM will help in adding and subtracting fractions.
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.
What types of problems can be solved using LCM?
Problems involving the addition and subtraction of unlike fractions.
Why would you want to rename fractions with the LCD?
Possible reasons: To add or subtract fractions, To compare fractions with different denominators.
What is the purpose of using lowest common multiple?
Finding the LCM helps you add and subtract fractions accurately.
What is the use of HCF and LCM?
The HCF helps when reducing fractions. The LCM helps when adding or subtracting fractions.
