If a sprinkler waters 1 over 12 of a lawn in 1 over 2 hour, how much time will it take to water the entire lawn? 7 over 12 hour, 1 over 6 hour, 6 hours, 10 hours

Using proportions, it is found that it takes 6 hours to water the entire lawn.

The rule of three is:

lawn - hour

1 lawn - x hours

Applying cross multiplication:

It takes 6 hours to water the entire lawn.

To learn more about proportions, you can take a look at link

on monday rodney ate 1/4th of the sandwich = 3/12

on tuesday he ate 1/3rd of the sandwich = 4/12

therefore in total he has eaten = 3/12 + 4/12 = 7/12

thus we can say that he has eaten 7/12 of the sandwich on monday and tuesday alltogether.
