the least common denominator of three fifths and two fifteenths and one sixth is 30. you multiply 15 by two, 6 by five, and 3 by ten.
You don't say how many ninths there are, which is critical to the total. Change the mixed numbers to improper fractions with the common denominator of 18 and proceed with the addition. Reduce if possible.
You need at least two denominators to find something in common between them.
three, because for one third three was the denominator , and for one sixth the denominator was devisable by three.
The LCM applies to whole numbers, not fractions. If you're trying to find the least common denominator, it's 12.
You need to:* Find a common denominator (it need not be the least common denominator); * Convert both fractions to the common denominator * After that, you can simply subtract the numerators. * Check whether you can simplify the result.
It is 5/18.
Denominator = numerator * 6.
One and one sixth
6/9 = 2/3
yep, they are, why do you ask that anyway
No. To find equivalent fractions, divide the numerator and denominator by the same integer. 3/9 divided by 3/3 = 1/3 (which is twice as large as 1/6)
