PLEASE HELP! GIVING POINTS :)!

Answer:

8 23/40

Step-by-step explanation:

8 and 5 have 40 in common. To get from 8 to 40 you need to multiply by 5. You have to do the same to the top and bottom numbers in the fraction. 3/8 turns into 15/40. To get from 5 to 40, you need to multiply by 8. Again, u have to do the same for the top and bottom. 1/5 turns into 8/40. 15/40 + 8/40 = 23/40. Add the whole numbers, 6 and 2, to get 8. So the answer in 8 23/40. Hope this helps!

muminat
I am guessing it is a rectangular room...
so a 5 x 3 1/4 meter room

The area of a rectangle is length * width
A = l * w
plug in the known
A = 5 * 3 1/4
A = 16.25, or 16 1/4

The area of Slater's?, or Slader's?, room is 16.25 meters^2

Hope this helps
