Well let's see how many numbers can be divisible by 6 or 8, add them up, and then put it into a fraction. 6: 6, 12, 18, 24, 30, 36. 6: 8, 16, 24, 32, 40. Total: 6, 8, 12, 16, 18, 24, 30, 32, 36, 40. There are 10/40 positive numbers that can be divided by 6 or 8. Simplified, 1/4.
Well a physical map is a map that shows things like elevation instead of state capitals. So you would probably see a feature like a scale. A scale showing you what color means what means what elevation.
Transformation means movement of objects in the coordinate plane. Transformation can be done in a number of ways, including reflection, rotation, and translation. Reflection is flipping an object across a line without changing its size or shape.
