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-





Ratio: 80:70

Percent: Girls: about 66% and Boys: about 46%

Fraction: Girls: 80/150 Boys: 70/150

Difference:150-80=70 and 150-70=80

Complete the following questions for a graded assignment!1. Explain what you think each word means when it is used to make a comparison.a) ratio-b) percent-c) fraction-d) difference –

Ratio: When you use a ratio for a comparision you either use part to whole or part to part and see is they are similar and compare them.
Percent: I think that percents are the easiests because you can see what your compareing and how many people acully like that and don't like it.
Fraction: Fraction is kinda like ratios because its like part to part or part to part and you reduse all fractions if they can be redused into a littler ratio.
Difference: You have to find the difference either between the ratio fraction or percent and compare them

1) What has to be the same in order for two parallelograms to be similar? 2) Describe a way to find a missing side length in a pair of similar figures. 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?

1. The side lenths have to be simlilar and two of the sides have to have the same angles.
2. One way you can find the missing side length is scale factor and another is ratios you divide top by bottom and then multiple and get the value of X
3.The other two side lengths are 10in because the scale factor is 2.5.
