#2 what number u divide to get 2??

OpenStudy (pyxieyt):

2. You need to multiply or divide to find the equivalent ratio

OpenStudy (pyxieyt):

3. To write a ratio as a unit rate you need to find out how many meters are in one second (you divide)

OpenStudy (anonymous):

can u help me

OpenStudy (pyxieyt):

Okay, lets start with (2). Do you want to try to multiply or divide to find the equivalent ratio

OpenStudy (anonymous):

multiply

OpenStudy (pyxieyt):

Do you think if you multiply you will get one of the answer choices?

OpenStudy (pyxieyt):

Lets look at 2a. Is 2:4 an equivalent ratio

OpenStudy (anonymous):

ummm... yes?

OpenStudy (pyxieyt):

Remember you do not have to guess! Why do you think it is A. ?

OpenStudy (anonymous):

umm Im not sure see im not good at math so yeah im sorry

OpenStudy (pyxieyt):

Lets multiply it by 2!

OpenStudy (pyxieyt):

Its okay you will get it (^o^)

OpenStudy (anonymous):

wait to I do 2 x 4?

OpenStudy (pyxieyt):

Yep! and do the same to the denominator

OpenStudy (anonymous):

2x4=8

OpenStudy (pyxieyt):

Yep! Now can you try to do the denominator ,too?

OpenStudy (anonymous):

whats the domitator?

OpenStudy (pyxieyt):

16 is the denominator :D

OpenStudy (anonymous):

ok

OpenStudy (anonymous):

okay do the bottow one is the demonator

OpenStudy (anonymous):

oh no i only have like 10 minutes left do u know all the answers? please help don't wanna be grounde by math teahcer

OpenStudy (pyxieyt):

Sorry I'll try to guide you through but I can't just give you answers (against the rules)

OpenStudy (pyxieyt):

So we know 2 will be C. Now lets look at 3!

OpenStudy (anonymous):

okay i will go tell my teacher to give me at least 30 minutes

OpenStudy (pyxieyt):

What is 8 divided by 10!

OpenStudy (pyxieyt):

With this you could just move the decimal to the left!

OpenStudy (anonymous):

it is 0.8

OpenStudy (pyxieyt):

Yep!

OpenStudy (anonymous):

ok

OpenStudy (pyxieyt):

Now to find unit rate for (4) instead of 5 1/2 you can put down 5.5 so it can be easier to divide

OpenStudy (pyxieyt):

so what is 286 divided by 5.5?

OpenStudy (anonymous):

okay i wrote down 5.5
