What is the least common denominator for 2 3 and 1 5?
15
What is the lowest common denominator for 15 and 24?
it is 120,8 times 15 equals 120 and 24 times 5
Which is greater two thirds or three fifths?
Two thirds are greater than three fifths.In order to answer this we have to convert both fractions into a common form to see which is bigger. To do this:* multiply the denominator (the number at the bottom of a fraction) of each fraction together to get a new 'common' denominator.* divide the new common denominator by the old denominator and multiply the result by the numerator (the number at the top) of the fraction you are converting to get a new numerator.So if we do this our common denominator is 15 (3 times 5). We can then convert two thirds in to fifteenths by dividing 15 by 3 (=5) and multiplying by 2 (=10). Thus 2/3 = 10/15.When we do this for three fifths we get: 15 divided by 5 times 3 = 9.Thus 3/5 equals 9/15.Therefore 2/3 is greater than 3/5 as 10/15 is greater than 9/15.
What is four fifths plus one third making the denominator the same?
seventeen over fifteen because the common denominator of 5 and 3 is 15 think about it like this: 4/5x3, 4x3=12, 5x3=15 1/3x5, 1x5=5, 3x5=15 so you get 12/15+5/15 see how they simplify back? then add the numerators and keep the denominator and you get 17/15 or 1 and 2/15
Common denominator for numbers 3 5 7?
1 is the only common denominator.
