What is the least common denominator for 2 3 and 1 5?
15
Common denominator for numbers 3 5 7?
1 is the only common denominator.
Arrange these fractions from least to greatest 5-9 3-4 7-12?
To compare fractions, we need to have a common denominator. In this case, the common denominator for 9, 4, and 12 is 36. Converting the fractions to have a denominator of 36, we get 20/36, 27/36, and 21/36. Therefore, in order from least to greatest: 5/9, 7/12, 3/4.
What is the least common denominator of 4 and 5?
The least common denominator of 4 and 5 is the smallest multiple that both numbers share. In this case, the least common denominator of 4 and 5 is simply their product, which is 20. This is because 20 is the smallest number that is divisible by both 4 and 5 without leaving a remainder.
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.
