<span>If you want to convert 15.1 into a fraction, you can do it like this:
15 <span>equals to 15</span>/1 <span>and </span>0.1 <span>equals to 1</span>/10
<span>The result is 15</span> 1/10.
If you want to make it a pure fraction, you have
to make one additional step:
<span>because you want to add 15/1 and 1/10, you
have to get the same denominators, so 15/1 changes to 150</span>/10.
<span>Now, you can add </span>150/10 and 1/10<span>.
The result is </span>151/10<span>.

Scale 1:2 means that 1 cm on the drawing is 2 cm in reality. So the square is 8cm x 8cm = 64cm².
Notice that while the size gets two times as big, the area gets 2²=4 times as big. That can be confusing. If you actually draw the square on 1:1 and also on 1:2, you can easily see that the latter fits 4 times in the real size...
Your answer is 560cm^2.
We get this answer first by dividing 96 by 2, because the perimeter is made up of 2 lots of both sides. This gives us 48cm.
Then we find out how long each side is by adding together 5 and 7 to give us 12, and dividing 48 by 12 to give us 4. This is how big each of the 'parts' of the ratio are. Then, we just multiply 4 by 5 to get 20, and 4 by 7 to get 28.
This tells us that 20 and 28 are the side lengths, so we just need to multiply them together to get the area of the rectangle, which gives us 560cm^2.
I hope this helps! Let me know if you have any questions :)
