Can you help me with my homework??? It takes Evan 6 3/4 hours to mow 3 lawns. It takes him 2 1/3 hours to mow Mr.gals lawn and 1 3/4 hours to mow Ms.lee's lawn. How many hours did it take to mow the third lawn?

6 3/4 - 2 1/3 - 1 3/4

6 9/12 - 2 4/12 - 1 9/12 = ?

3 1/4

I got a 0/2 on the question I was doing but the answer will help A LOT!

Thanks

I was so confused about this question but, you have to rename the fractions to get the answer.

its 4 u noobs

Of course! To find out how many hours it took to mow the third lawn, we can start by figuring out how many hours it took to mow the first two lawns.

According to the information given, Evan takes 6 3/4 hours to mow 3 lawns. This means that the average time it takes to mow each lawn is 6 3/4 divided by 3. To simplify the fraction, we can convert 6 3/4 to an improper fraction, which is 27/4.

So, Evan takes (27/4) divided by 3 hours to mow each lawn.

To find out how long it took to mow Mr. Gal's lawn, we need to multiply the time it takes to mow each lawn by the number of lawns he mowed. Since it took (27/4) divided by 3 hours to mow each lawn, it would take (27/4) divided by 3 multiplied by 1 1/3 (2 1/3 as an improper fraction).

To multiply fractions, we multiply the numerators (the top numbers) together, and multiply the denominators (the bottom numbers) together.

So, (27/4) divided by 3 multiplied by (4/3) gives us:
(27/4) * (4/3) divided by 3.

By simplifying the fraction, we can cancel out the common factors of 4:
27 * 1 divided by 3 * 1.
This leaves us with:
27 divided by 3.
Which simplifies to:
9.

So, it took 9 hours to mow Mr. Gal's lawn.

Similarly, to find out how long it took to mow Ms. Lee's lawn, we need to multiply the time it takes to mow each lawn by the number of lawns. Since it took (27/4) divided by 3 hours to mow each lawn, it would take (27/4) divided by 3 multiplied by 1 3/4 (1 3/4 as an improper fraction).

So, we need to multiply:
(27/4) * (4/3) divided by 3 multiplied by (7/4).

Again, we can cancel out the common factors of 4:
27 * 7 divided by 3 * 1.
This gives us:
189 divided by 3.
Which simplifies to:
63.

So, it took 63 hours to mow Ms. Lee's lawn.

Now, to find out how many hours it took to mow the third lawn, we subtract the combined time it took to mow the first two lawns from the total time (6 3/4 hours or 27/4 hours).

So, we have:
27/4 - (9 + 63).

Adding 9 and 63 together, we get:
72.

Now we subtract 72 from 27/4:

27/4 - 72/1 = (27 - 288) / 4.

27 - 288 equals -261, so we have:
-261/4.

Therefore, it took -261/4 hours to mow the third lawn.

Please note that negative time does not make sense in this context, so it's possible that there was an error in the given information or calculations.
