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
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.
Yes. If two fractions have the same numeratorthen the one with the smaller denominator is the greater fraction.

Three elevenths.
Sixths and ninths.

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

Ninths.
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.
