Same as finding the LCM of 6, 5, 7:
2*3*5*7 = 210
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.
one-sixth plus two-fifths is changed to 5/30 plus 12/30 because you must find the common denominator then add them. So the answer is 17/30 which is as low as it will go.2/5 + 1/6 = 12/30 + 5/30 = 17/30
Answer: Two fifths, one sixth, and then one third.
Yes, because if you multiply the nominator and denominator of three fifths by two you get six tenths. 3 times 2 = 6. 5 times 2 = 10. So 3/5 is equal to 6/10.
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.

three, because for one third three was the denominator , and for one sixth the denominator was devisable by three.
one-sixth plus two-fifths is changed to 5/30 plus 12/30 because you must find the common denominator then add them. So the answer is 17/30 which is as low as it will go.2/5 + 1/6 = 12/30 + 5/30 = 17/30
five sevenths obviously.
24
30
one-sixth
one twelfth
6/7 ÷ 3/7 = 2
Two fifths is 140% more than one sixth.
No sixth sevenths is bigger :D hope i help
