Hi there!
To solve this problem, we need to divide 67.8 by 6 to find the amount of hours each day.
67.8 / 6 = 11.3
You worked 11.3 hours each day.
Hope this helps!
Ok what am I supposed to answer?
First you had to rewrite the problem with eighteen as the three times six is equal to eighteen.
Then you factor it out by the common term of six.
Final answer: 
Hope this helps!
And thank you for posting your question at here on brainly, and have a great day.

Hi there!
Usually, the amount of flour varies between different cookie recipe's, but if you're going to make the normal chocolate chip cookie, into a batch of 60, you'd need 4 cups of flour.
So, 4 cups of flour would make your 60 chocolate chip cookies.
Hope this helps! :D
