78/9 - 25/6 = 71/9 - 17/6 = 142/18 - 51/18 = 91/18 = 51/18

To compare four sixths (4/6) and five ninths (5/9), we can simplify both fractions. Four sixths simplifies to two thirds (2/3), while five ninths also simplifies to five thirds (5/9). Since 2/3 is not equal to 5/9, four sixths is not equal to five ninths.
11/6 minus 2/9 is 1 11/18

5/9 minus 1/3 is 2/9
You have to convert your fractions so that they are all the same. In this case, we can use sixths. So two and three sixths (two and a half), minus one and four sixths (one and two thirds), would equal five sixths. Another way to do it is to convert the whole numbers to sixths as well. Fifteen sixths minus ten sixths equals five sixths.

5/9 minus 2/3 equals -1/9
Two thirds minus two ninths is 4 ninths. Two thirds is 6 ninths. 6 ninths minus 2 ninths is 4 ninths.
