A fraction is a numerical quantity that is not a whole number.What you probably need to relearn is equivalent fractions, Least common denominator and how to multiply and divide fractions.
-20/48 x 6 =

x

I would cancel out the 6 in the numerator and the 48 in the denominator
Now I have <u />

or <u />

reduced.
-5 ÷ 2 = -2 1/2 and that is the answer in simplest form
I'd say yes. If you use the diagonal as a reference. Take the square and set your compass to the width of the diameter of the square. Now put it on the page and mark a point. Put the point of the compass on that mark and make another mark. Now you can connect the two marks with the straight edge and you have a line that, if you made a square with sides that long, it'd have 2x the area of the first one. That's because the diagonal is the square root of 2 larger than one side. Square the square root of 2 and you've got 2. You lust need to make a perpendicular line to the first one to get the box going.
The slope is:8
Because
M=rise/run
Or
Y2-Y1/X2-X1
Sooo…
-8-0/-3-(-2)
Or 8
Hope this helps:)
