comparing and scaling inv. 1 math reflections

1. Explain what you think each word means when it is used to make a comparison.a) ratio-b) percent-c) fraction-d) difference –2) Give an example of a situation using each concept to compare two quantities. (150 total seventh graders, 80 girls, 70 boys)a) ratio-b) percent-c) fraction-d) difference-


A ratio is part to part 80/150

B percent is a # out of 100 70%

C fraction 70/150

D defference 150-70=80

Answer the following questions on YOUR blog as a post. Use the same title as mine for your post. Write your answers in complete sentences! An easy way to do this is to copy and paste the questions below onto your post and then put your answers in a different color!1) What has to be the same in order for two parallelograms to be similar? The angles and you have to have the same ratios for the parallelograms to be similar.

2) Describe a way to find a missing side length in a pair of similar figures. You have to find the scale factor and then do scale factor times what = missing side length

3) I have a small isosceles triangle with a base of 3 inches and other sides are 4 inches.I want to create a similar isosceles triangle with a base of 7.5 inches.What should the other side lengths be and why?
The other side lengths should be 10. they should be 10 because sf is2.5 and 2.5 times 4=10

1) Think back to Mug Wump - how did you decide which characters were similar to him? How did you decided which characters were NOT similar to him?

2) If I used (x, y) to create Mug and I used (4x, 4y) to create a new character, Pug, how would Pug be similar to Mug? What is the scale factor from Mug to Pug? How many Mugs would fit into one Pug (area)?

1) i decieded which ones were similair by seeing what the sf is.i decieded which ones were not similair by deviding them.


2) the sf from mug to pug would be times 4. four mugs could fit in pug.
