Question

Perform the indicated operation 5 1/6 - 2 2/3

Answer 1

2½

Explanation:

First find the Least Common Denominator [LCD], which is 6, then convert 5⅙:

5⅙ → 4 7⁄6

`5 (1)/(6) - 2 (2)/(3) = 4 (7)/(6) - 2 (4)/(6) = 2 (3)/(6) = 2 (1)/(2)`

You see, we regrouped 1 from 5⅙ to make sure that the top mixed number had a higher value than the bottom mixed number, so it is much easier to work with.
