If jake can install 12 snowplows in 8 hours, and Arthur can install 12 snowplows
in 12 hours, approximately how many plows can both of them install in 8 hours
working together?

The LCM of 8 hours and 12 hours is 24 hours.

jake can
install 12 snowplows in 8 hours,

 so Jake can install 36 snowplows in 24
hours.

Arthur can install 12 snowplows in 12 hours,

 so Arthur can
install 24 snowplows in 24 hours.

approximately how many plows can both of
them install in 8 hours working together?

 So together they can install 60
snowplows in 24 hours. So in 8 hours they can install 20 snowplows.
