@skullpatrol Am I correct? I don't want to be giving them the wrong directions.

- skullpatrol

You @Liv1234 are correct:
Any time you are asked for how many times one thing goes into another ...

- Liv1234

Alright. Thank you for reassuring me.

- anonymous

should i divid 4 1/2 and 45

- Liv1234

I already solved the problem, but I don't want to say what it is.

- Liv1234

I think you should be converting 4 1/2 into a fraction.

- anonymous

o i hate fraction's

- Liv1234

You multiply 4 by 2 and then add 1.

- Liv1234

When you get the answer to that you put that number over 2.

- Liv1234

Or to be exact, multiply the denominator by the number and then add that to the numerator.

- anonymous

so 4x2=8 and 8 plus 1 equals 9

- Liv1234

Right!

- skullpatrol

yes, now put the 9 over 2

- Liv1234

9/2 (:

- Liv1234

That isn't your answer, but that's the fraction you need to help you solve the answer.

- skullpatrol

4 1/2 = 9/2

- anonymous

so i divid now 9 divid 45

- Liv1234

No.

- Liv1234

You are going to multiply.

- anonymous

o yyy

- Liv1234

If I am not mistaken, it would be something like 9/2 * 45

- Liv1234

\[9/2 * 45\]

- Liv1234

Whenever you divide fractions, you end up multiplying them.

- Liv1234

So, 45/1 * 2/9 (because I think you flip the reciprocal)

- anonymous

were did the 2 come from in 9/2

- Liv1234

The mixed number.

- skullpatrol

|dw:1449970071286:dw|

- Liv1234

And when you multiply that, what do you get?

- Liv1234

\[45 * 2/9\]

- Liv1234

Whenever you divide fractions, you always multiply the reciprocal. That means you flip the fraction, which is why it is 2/9. Then you multiply.

45 would turn into 45/1 right

- skullpatrol

yes

- Liv1234

45/1 is the same thing as 45.

- anonymous

ok

- Liv1234

If it was 1/45 it would be different, but it is 45/1 or 45 in this case.

- anonymous

so the answer is 10/1

- Liv1234

10.

- skullpatrol

:D

- anonymous

right

- Liv1234

Correct.

- anonymous

so the total answer is 10

- Liv1234

Yes.

- anonymous

thank's

- Liv1234

I actually enjoyed that.

- Liv1234

I mean walking through the problem lol.

- Liv1234

It refreshed my memory of fractions.

- anonymous

- anonymous
