Well, honey, to rewrite 5/8 and 7/10 with the least common denominator, you first need to find the least common multiple of 8 and 10, which is 40. Then, you can rewrite 5/8 as 25/40 and 7/10 as 28/40. Voila! Now you have them both with the same denominator, making it easier to compare those sassy fractions.

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.
1. 2 3/5+ 3 4/5 Rewrite the mixed numbers as fractions; = 13/5 + 19/5 Write the sum of the numerators over the common denominator; = (13 + 19)/5 = 32/5 Rewrite the fraction as a mixed number; = 6 2/5 2. -2 1/5 + (- 4 5/8) Rewrite the mixed numbers as fractions; = -11/5 + (-37/8) Multiply by 8/8 the first fraction, and by 5/5 the second fraction in order to have the same denominator (because LCD is 40); = -88/40 + (-185/40) Write the sum of the numerators over the common denominator; = -(88 + 185)/40 = -273/40 Rewrite the fraction as a mixed number; = -6 33/40
No because if you find a common denominator (6) then 2 over 3 would equal 4 over 6.
5 over 7 is greater than 3 over five. You have to find a common denominator. The common denominator is 35 so 5 over 7 would become 25 over 35 and 3 over 5 would become 21 over 35. 25/35 > 21/35 = 5/7 > 3/5
4/17 can be written 40/170, and 3/10 can be written as 51/170. When written that way they have (least) common denominator 170.
At least two fractions are needed to determine a least common denominator.
You need at least two fractions to determine a least common denominator.
The least common denominator would be 50
At least one other fraction is needed to determine a common denominator.
You need at least one more fraction in order to have a common denominator.
A common denominator, though not the least one, is 200.
Two or more fractions or mixed numbers are required to have a least common denominator.
At least two fractions are needed to determine a common denominator.
The least common denominator between fractions 1 over 32 and 8 over 64 is 64.
There is no exact least common denominator. Six does not go into 38
Least common denominator is used for fractions, not integers. Integers can be expressed as fractions, though, by placing them over 1 so if you really meant least common denominator then the answer is 1. If, however, you meant least common multiple, then then answer is 60.
