Josh needs 2/3 hour to weed a garden and 1/12 hour to water the garden. What part of an hour do these two jobs take?

All we're doing is working with fractions.

2/3 is the equivalent of 8/12.

So if we add the fraction 8/12 and 1/12, we should get 9/12.

If the problem asks you to simplify, the answer is 3/4.

So yeah, 45 minutes is the answer.

2/3 is the same as 8/12 is 8/12+1/12 is 9/12 which is also 3/4 or 45 mins
