Step-by-step explanation:
Louis made 24 quarts of lemonade, and he divided it equally into 6 pitchers.
Then, each pitcher must has a sixt of the total amount of lemonade, this is:

The old photocopier can make x manuals in an hour. The new photocopier can make 4x. Combined, they made 5x manuals in an hour.
In one hour they can make 1/28 of the manuals.
1/(28*5)=1/140 is the rate.
The new photocopier can make all the manuals in 4/140 or 35 hours.
The old one can make them in 140 hours.
