If Neil Works 3/4 of an hour on Monday and 6/10 of an hour on Tuesday how much time will she work altogether?

A. 19/14 hour

B. 19/20 hour

C. 1 7/20 hours

D. 1 7/10 hours

C

Step-by-step explanation:

3/4 + 6/10

Find a common denominator and find what you multiply to each denominator to get that number and multiply the numerator by the same amount

(3/4 * 5/5) + (6/10 * 2/2) =

15/20 + 12/20

Then add

15/20 + 12/20 = 27/20

Then finally convert to mixed number

27/20 = 1 7/20
