80 because 65+35 equals 100 then 180-100 is 80
In order to find the scale they are using first you must divide 12 by 3.75.
But since we get to estimate, the 3.75 will be made into a 4 because it's the whole number closest to 3.75.
12/4=3
Take your 3 inch scale and multiply it by 3 (we are using 3 instead of 2.8 because it's a whole number) to get the real life fence size.
3x3=9
The fence is about 9 feet.
No 1.2 x 2.6 doesn't equal 31.2 it equals 3.12
Yes, they're equivalent values.
Hope this helps!
