the least common denominator would be 15. 1/5 would be 3/15 and 2/15 would stay the same..2/15. you take the denominator and multiply it by what to get 15........????........ answer: 3. so you also would multiply the numinator by 3 then take the second one. you multiply the denominator by 1 to get 15 so you do the same with thge numerator. the common denominator is 15 but to get them to fractions with the same denominators you would do that.
The LCD of 0.9 (9/10) and 1/45 is 90.
The common denominator of three fourths and one fifth is twenty. The fractions including the common denominator can look like this: 3/4 to 15/20 and 1/5 to 4/20. Hope this helps!! ^^

One-third is the same as five-fifteenths. Two-fifths is the same as six-fifteenths. Five-fifteenths plus six-fifteenths is eleven-fifteenths. One, or fifteen-fifteenths, minus eleven-fifteenths is four-fifteenths.
To subtract fractions, you need a common denominator. In this case, the least common denominator is 20. Four tenths is equivalent to eight twentieths, and one fifth is equivalent to four twentieths. Therefore, eight twentieths minus four twentieths equals four twentieths, which can be simplified to two fifths.
3 fifteenths as a simplified fraction is 1 fifth. All you have to do is divide the numerator and the denominator by the greatest common factor.

When you have your two fractions you multiply the denominators to get the common denominator. So you would do 3x5=15, 15 is the common denominator. Now you cross multiply. you do 3x2=6 then 5x1=5. Now you have 5 fifteenths and 6 fifteenths. 5 fifteenths belongs to 1 third and 6 fifteenths belongs to 2 fifths. So now you can see that 2 FIFTHS is BIGGER than 1 third. ==================================== Or you could just convert the fractions into decimal form and see which one is bigger. 1/3 = 0.3333 2/5 = 0.4 <=== This one is bigger than 0.3333.
