Answer: I’ll explain it in simpler terms for you. A proportional relationship is one in which two quantities vary directly with each other. Ratios are proportional if they represent the same relationship. One way to see if two ratios are proportional is to write them as fractions and then reduce them. If the reduced fractions are the same, your ratios are proportional. An example of a proportional relationship is simple interest, tax, markups and markdowns, gratuities and commissions, fees, percent increase and decrease, percent error. Hope this helps! :D
Part 1: should be C. Because the question said 1.2 added to a number.

Step-by-step explanation:
Since Chloe collected 4 times as much as her friend, who collected 1/6 a bag, you will have to multiply 4 by 1/6 to find how much Chloe collected.
To multiply fractions, you multiply the numerators and multiply the denominators. Then you put the product you got from multiplying the numerators over the product you got from multiplying the denominators. Remember that 4 is the same as 4/1. Simplify the product if needed.:
Chloe collected 2/3 of a bag.

Step-by-step explanation:
Cars that are less than 19 mpg : 16, 18
2 cars have less than 19 mpg.
2/10 cars have less than 19 mpg.
To change fraction to percentage :
divide the numerator by the denominator, then multiply the decimal by 100
2/10 = 0.2
0.2*100 = 20
