Part 1 :

Ratio- A ratio shows the relative sizes of two or more values.

Ex. Word ratio- SUV's to Ferari's

Rate- is a ratio that compares two quantities of a different units.

Ex: On a vacation, Linda's family traveled 495 miles at 55 mph. How long did the trip take?

495miles/55mph= 9miles/mph

Proportion- is an equation stating that two ratios are equivalent.

Ex.

3*7=21 and 5*7=35. So the answer is 21/35.

Part 2:

1. 5 hours to travel 360 kilometers is about _____km/h.

Answer: Divide 360 by 5. Then you will get 72.

72km/h.

2. Emma saves 28 cents of every dollar that she earns. Emma earned $75 last week. How much money did Emma save last week?

Answer: 0.28 * 75= 21. Emma saved 21 dollars last week.

Part 3:

What are the three ways you can prove that equivalent ratio statements are true?

1.) 3/4 = 12/16 is an equivalent fractions because 3*4=12 and 4*4=16 which equals to 12/16. And if you divide 12 and 16 by 4 it equals to 3/4 so it's equivalent.

**3/4 = 12/16**or**4/9 = 16/32**1.) 3/4 = 12/16 is an equivalent fractions because 3*4=12 and 4*4=16 which equals to 12/16. And if you divide 12 and 16 by 4 it equals to 3/4 so it's equivalent.

2.) 4/9 are not equivalent fractions because 4*4=16 but 9*4=36.

3.) And if you use cross multiplication 3/4 = 12/16 there both 48 while 4/9 = 16/32 is 128 and 144 so it's not equivalent.

Part 4:

Find a video about using proportion and embed it in your post. Make sure you select the small size of the video.

Part 5:

1.) Does this seem fair? No, because the homeless man just steal a $100 from the bank but he surrendered himself to the police because he felt guilty for stealing it. While the CEO guy just steal 3 billion dollars and he was sentence for about 40 months! That isn't fair.

2.) With what you know about

**proportion**look and read what is in the image above. Does it seem just and fair? No, it's unfair because that homeless man will be in 15 years on prison just by stealing a 100 dollar bill. While that CEO guy just steal a billion dollar yet only a 40 months sentence. Maybe that CEO guy is rich and bribe the judge to lessen his sentence.
3.) Why have you made this choice? BECAUSE IT'S UNFAIR. First of all that CEO guy stoled 3 billion dollars and yet 40 months while that homeless guy just stole a $100 and he confessed it to the police. 3 billion and $100 is a HUGE difference.

4.) What would you have done if you were the judge. First of all if that CEO guy just bribe me to lessen his sentence. I'll give him a big slap in the FACE. And as for the CEO guy I will give him the 15 years in jail. While that homeless guy about maybe lesser than 30 months because he did confess after all.

**Bonus:**

How tall is the tree near the kid ?

Well if he's 13 he's average height would be 5.25 feet. And he looks like he would fit with three of him. 5.25 * 3=15.75. Maybe 15.75 just a guess.
