Mathew worked 5/6 hour on Monday, 3/4 hour on Tuesday. How many hours did he work on Monday and Tuesday?

He worked 19/12 hours.

10/12 + 9/12 = 19/12

To find the total number of hours Mathew worked on Monday and Tuesday, we need to add the number of hours he worked on each day.

Mathew worked for 5/6 hour on Monday and 3/4 hour on Tuesday.

To add these fractions, we need to find a common denominator. We can multiply the denominators 6 and 4 together to get 24, which is the least common multiple (LCM) of the two denominators.

Now, we can convert the fractions to have a common denominator of 24:

5/6 = (5/6) * (4/4) = 20/24
3/4 = (3/4) * (6/6) = 18/24

Now that both fractions have a common denominator, we can add them:

20/24 + 18/24 = (20 + 18)/24 = 38/24

Since the numerator (38) is greater than the denominator (24), we can simplify the fraction:

38/24 = 1 14/24

So, Mathew worked a total of 1 hour and 14/24 (or 1 7/12) hour on Monday and Tuesday combined.
