Answer 1

1 1/3 hours

Explanation:

So we are trying to find 1/4 of 5 1/3

the easiest way to do this is to make the mixed number into a fraction then multiply the other fraction.

5* 3 = 15

15 + 1 =16

5 1/3 = 16/3

now we find the answer

16/3 * 1/4 = 16/12

making this into a mixed number we get

16/12 = 1 4/12 = 1 1/3

we can check this answer by multiplying it by four

1 1/3 * 4 = 4 4/3 = 5 1/3
