But maybe the easiest is to start with the ratio that they gave us, where they gave us both the numerator and the denominator, and then move from there. And we see from the denominator, we doubled the denominator. So we would double the numerator as well, and so you would get 48. These are all equivalent to 18/55, so all of these. So you have this situation where we see 27/75 is 54/150. So 54/165 is smaller than 54/150, which tells us that 18/55 is smaller than 27/75. So this is saying that 27/75 is greater than 18/55, and that is absolutely right. Which of these tables might show the distances one of Lunara's friends traveled over time? Each of them runs at a constant speed starting at time 0. If you multiply the distance by 5, we're multiplying the time by 5. So table 3 doesn't seem to make sense, either. So that's the same thing as-- let's see, that's the same ratio as, if we were to divide by 2, as 7 to 5 ratio.
So for example, if we look at this one right over here, the numerator is 12. So the denominator is also going to be half of the denominator here. And what we just did here is we wrote four equivalent ratios. The following table shows equivalent fractions to 27/75. And over here, we see that 18/55 is 54-- and this 54 jumped out at me because it's the same numerator-- over 165. If we divide both of these by 3, this is also a 7 to 5 ratio.
So all I would do is flip both sides of this equation right here to get this one over here.
You could also think about the ratios in other ways. So we have the ratio between the number of apples, 7, and the cost of the apples, 5, is going to be equal to the ratio between another number of apples, which is now x, and the cost of that other number of apples. And so notice here in this first situation, what was unknown was the cost.
The ratio 3 to 5 or 3/5 is the same thing as 12 to 20, is the same thing as 24 to 40, is the same thing as 48 to 80. So then they wrote all of the different equivalent fractions. And if you divide both of these by 7, this is also a 7 to 5 ratio.
So table 4 seems like a completely reasonable scenario. We do not ask why you are unable or not willing to do it on your own once you contact us with words like “Help me do my homework.” You must have your reasons, and our main concern is that you end up getting a good grade.It does not matter to us, whether you are too busy at work, concentrating on a passion project, or simply tired of a seemingly infinite flow of assignments.And then you would just have to essentially solve for x. And we could do all of the different scenarios like this. So if we have 5 people for 2 eggs, then for 15 people, we are going to need x eggs. So all of these, we've essentially set up the proportions that describe each of these problems.You could also say the ratio between 7 apples and x apples is going to be the same as the ratio between the cost of 7 apples and the cost of 8 apples. And then you can go later and solve for x to actually get the answer.Jayda takes 3 hours to deliver 189 newspapers on her paper route. What is the rate per hour at which she delivers the newspaper? But we want to figure out the rate per hour, or the newspapers per hour, so we can really just flip this rate right here. If you're behind a web filter, please make sure that the domains *.and *.are unblocked.I never needed anyone to do my homework for me until I got a part-time job in college.So this first sentence tells us that she delivers, or she takes, 3 hours to deliver 189 newspapers. So if we were to just flip it, we would have 189 newspapers for every 3 hours, which is really the same information. We're just flipping what's in the numerator and what's in the denominator. So let's divide this numerator and this denominator by 3 to simplify things.
