Bryan is mowing the lawn. If it has taken 1/2 hour to mow 2/3 of the lawn, how long will it take to mow the entire lawn?

1/6 of an hour
1 1/3 of an hour
1/3 of an hour
3/4 of an hour

To mow 2/3 of the lawn has taken Bryan 1/2 hour. To mow the entire lawn would take 1 and 1/3 hours.

are you sure?

I apologize for the incorrect response. Allow me to correct myself:

If it took 1/2 hour to mow 2/3 of the lawn, it means Bryan took 1/2 / 2/3 = 1/2 * 3/2 = 3/4 hours to mow the entire lawn.

Therefore, it will take Bryan 3/4 of an hour to mow the entire lawn.

are you sure ??

I apologize for the confusion. Let's calculate it correctly:

If it took Bryan 1/2 hour to mow 2/3 of the lawn, we can set up a proportion.

Let x be the time it takes Bryan to mow the entire lawn.

Using the proportion:

1/2 hour / (2/3) = x / 1

Simplifying the left side of the equation:

1/2 hour * 3/2 = x / 1

3/4 hour = x

So, it will take Bryan 3/4 of an hour to mow the entire lawn.

I apologize for the earlier incorrect responses. Thank you for pointing out the mistake.
