We know that there are 100 cm in 1 m. We can convert 0.75 m to cm by multiplying by 100 to give us:
Therefore the path before the addition is 75 cm wide.
Mr. Kassel added 20 cm of blocks on each side of the path, meaning that the added width is actually 40 cm total (20 on each side, and there are 2 sides).
So we need to add 40 cm to the original 75 cm:
So now we have the width of the path in cm, the question asks for the width in meters. We can do this by dividing the width in cm by 100 to get the width in meters:
Now we know that the new width of the path is 1.15 m.

For one thing, Cal and Martha are <em>technically</em> in agreement; 0.1 and 0.10 are the exact same value. To see whether they're right, or whether Angela had it correct, let's take a look at the numbers 0.5 and 0.2.
As fractions, those two values would be
and 
, or 
and 
when reduced. When you cut the original pizza in half, you cut it into <em>2 equal slices</em>. Cutting each of those two pieces into <em>5 equal pieces</em>, we get a total of 5 x 2 = <em>10 equal slices</em>. So, taking one of those slices at that point - as Angela did - would be taking 
- or 0.1 - of the whole pizza.
So, both Cal and Martha are correct.
