Answer 5

rehana pays $284 in tax. this is 2/9 of the money she earns, how much money does rehana have?

Answer 6

...

Answer 7

She has $1278 in total

Answer 8

how did u get it?

Answer 9

I did it by forming an equation

Answer 10

Look first of all the ratio is 2:7. Lets have x be the total. 2+7=9 so 2/9 multiply the x will give you 284. x= 284 divided by 2/9 which will give you 1278. You can check it by multiplying 2/9 by 1278 which will give you 284.

Answer 11

aha

Answer 12

Did you understand??

Answer 13

kind of

Answer 14

It is very related to fractions, but I don't think that that is the best way to think of ratios.

Instead, think of how two quantities are related to each other. So, for example, if I'm asking about the ratio at a party, I'm thinking about how two quantities are related. Which two quantities might I be thinking of? Well, I'm a creep, so I'm thinking of number of guys and number of girls.

A party with a good girl:guy ratio has a lot of girls COMPARED TO the number of guys.

Now it's important to understand that I'm not purely talking about the number of girls. A party with a lot of girls could have a good ratio, or it could have a bad ratio, depending on the number of guys there.

Answer 15

10 girls is good if there are 2 guys, but 10 girls is bad if there are 30 guys.

Answer 16

yeah

Answer 17

Another example of a ratio is GAS MILAGE.

Again, we're comparing two quantities. So what two quantities would we be comparing in this case? Well, we're comparing miles traveled and gallons of gas burned. Traveling 30 miles could be good, if I only burned 1 gallon to do it. That would be a ratio of 30:1, or 30 miles per gallon.
Or, traveling 30 miles could be bad, if I burned 10 gallons to do it. That would be a ratio of 30:10, or 3:1, which is 3 miles per gallon.

Answer 18

Now, think about making lemonade, and see if you can explain to me how ratios would be important in making delicious lemonade.

Answer 19

Answer 20

do you mean ratio of lemon juice to water when making lemonade for example?

Answer 21

Yes, very good =)

Answer 22

I probably would have though of the ratio of lemons to sugar, but lemon juice to water is important also.

Answer 23

Answer 46

Sarah, imagine making some lemonade.
You sit down, and you put 3 lemons in, and you take a sip. It's a bit strong. What do you do next?

Answer 47

okay i am out

Answer 48

add some sugar?

Answer 49

Let's ignore sugar for now =)

Answer 50

ok :)

Answer 51

Imagine it's kool-aid lemonade. There's only 2 ingredients. Water and koolaid mix.

Answer 52

add water?

Answer 53

Okay, so you put in some water, and you put in 3 packs of koolaid mix. It's too strong. So you add water. Exactly.

Answer 54

yeah

Answer 55

So you haven't changed the amount of koolaid mix at all, but the drink has gotten less strong. What changed? The ratio.

Answer 56

So think about making koolaid and you mix
1 gallon of water and 3 packs
and you really think that tastes perfect, but you are having a party, so you need 3 gallons. How do you manage to make 3 gallons of koolaid that tastes the same?

Answer 57

um..you add 3 packs of koolaid in each gallon..i guess

Answer 58

Great! So if I use 3 gallons of water, how many packets total?
