Answer:
this is the first questionn.
I hope this honestly helped . if not tell me your question in details thank you.
Explanation:
Example: “Yesterday, I put 10 gallons of gas in my car and I paid $30. A couple hours after, I went back to the gas station with my dad’s car and after filling up the tank, I paid $18. How many gallons of gas did I put in my dad’s car?”
In order to solve this problem, first we’ll have to figure out the proportionality ratio between the gallons I put in my car and the amount I paid.
$30 ÷ 10 gallons = $3/gallon ($ per gallon)
After, once we know that the ratio is $3/gallon, we need to calculate how many gallons we can put in the tank with $18.
$18 ÷ $3/gallon = 6 gallons
So then, the second time I went to the gas station, I filled my dad’s car with 6 gallons of gas.
This situation illustrates a clear example of proportional relationships where the quantities of the first fill up are proportional to the ones of the second fill up; the quotient that comes from dividing both of them is the same in both cases: it’s the ratio:
I hope that you can start to see everyday “ratio and proportion” phenomena with the help of this post.
