How do we evaluate 5 3/4 x 1/3

Change 5 3/4 to 23/4 because we did 5 (4) = 20, 20 + 3 = 23. We kept the denominator the same

So, your problem becomes

23/4 * 1/3 = ?

23 (1) = 23

4 (3) = 12

Fraction becomes: 23/12

Then we change it to a mixed number: 1 11/12

So, therefore, your answer would have to be

1 11/12
