PART 1
1) part-to-part

2) percent of the part to the whole of the problem

3) part-to-whole

4) to subtract the numbers. ex. 45 students - 6 students = 39 students

PART 2
1) 17,000 soilders-to-30,000 rifles

2) 56% of the soilders have rifles

3) 17,000/ 30,000

4) the difference is 13,000 rifles

1) For two parrallelograms to be similar, the angles can't change, and the scale factor has to be even (works for the both of them).

2) To find a missing side length, one way is to find the SF then divide the SF into the corrosponding side to fins the missing side length.

3) The side lengths that are missing are both 10 inches long. The scale factor is 2.5, I know this because 7.5 is 2.5

Math reflections

The paper that measures 8in by 10in will be reduced in the copier by a 50% ratio to the side lenghts of 4in by 5in. This is because you are taking the two numbers and splitting them in half.
The angles of the new paper will not differ from the old paper because the angles always stays the same on enlarged or reduced images. The area of the new will 1/4 the area of the original. The area of the original is 80in2 the new reduced image is 20in2. 20in is 1/4 of 80in.

MUG WUMP

1) When I decided which characters are similar to mug wump I looked at the scale factor. If the scale factor was (4x,45y) the character would be not similar because the length of the character would be far from the same. If the scale factor was (4x,4y) it would be similar because only the size would be disstorted.

3) Pug would be similar to mug but only four times as large. The new figure will have four mugs inside of him and the area will be 4 times as large
