George worked on his science project for a total of 2 2/3 hours. he worked on it for 5/12 hour on monday and 9/12 hour on tuesday. he finished the project on wednesday. how long did george work on his project on wednesday?

The answer is 1 1/2. To find it you first add 9/12 and 5/12 which equals 14/12 then you make it a mixed fraction which is 1 2/12 which can simplify to 1 1/6. Next you make the denominator of 2/3 and 1/6 equal, so you multiply 2/3 by 2 and you get 4/6 so you now have 2 4/6 and 1 1/6, now you subtract them both which is 1 3/6 which simplified is 1 1/2

Both of them are correct.

The perimeter is found by adding up all four sides. If you notice, one of them is width and one of them is length. A rectangle has four sides, two width and two length.

l= length and w=width so P=2l+2w.

But, we can combine them by factorizing 2l+2w.

Lets see what we can pull out. We can only pull out 2.

2(l+w)=2l+2w.

2(l+w)=P

Both of them are correct.

Hope this helps plz hit the crown :D
