you have to find a common multiple so the easiest way to do that is times them together.
2 5

11 x 9 99
then 11x5 and 2x9
18 55

99 99

Yes. Convert the fractions to a common denominator, then you can easily compare. Or convert them to decimals - that's easy with a calculator. That also lets you compare easily.
To add the fractions five ninths and negative three eighths, you need to find a common denominator. The least common multiple of nine and eight is 72. Convert both fractions to have a denominator of 72 and then add the numerators. The result is -17/72.
31 over 99ths.
Only fractions with the same denominator can be added directly. Addition of such fractions can be achieved by adding their numerators to form the numerator of the sum, with the common denominator of the added fractions constituting the denominator of the sum. In this instance, 2/3 = 6/9, and 4/9 + 6/9 = 10/9.
To compare two fifths (2/5) and four ninths (4/9), we can convert both fractions to a common denominator or calculate their decimal equivalents. Two fifths is equal to 0.4, while four ninths is approximately 0.444. Since 0.444 is greater than 0.4, four ninths (4/9) is greater than two fifths (2/5).
To subtract two fractions, they must have a common denominator. In this case, the common denominator is 9. So, convert 2/3 to 6/9. Then, subtract 6/9 - 4/9 to get 2/9 as the result.

6/18 and 9/27......you can find out equivalent fractions by multiplying the numerator (top number) by the same number as the denominator (bottom number)
Change both numbers to single fractions with a common denominator of 117
Yes. If two fractions have the same numeratorthen the one with the smaller denominator is the greater fraction.
