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 adding or subtracting two fractions with denominators that are not equal what is the first step you take?
When adding or subtracting fractions with different denominators, the first step is to find a common denominator. This involves finding the least common multiple (LCM) of the two denominators. Once you have a common denominator, you can then add or subtract the numerators of the fractions accordingly.
How is adding like fractions and adding unlike fractions the same?
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.
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.
Is 2 over 5 more than 3 over 7?
I suggest you do the following: 1) Find a common denominator of 5 and 7. (It need not be the least common denominator; multiplying the two denominators works for our purposes.) 2) Convert both fractions to equivalent fractions with this denominator. 3) Compare the numerators of the fractions thus converted.
