@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
  • Liv1234
Alright. Thank you for reassuring me.

  • anonymous
should i divid 4 1/2 and 45
Liv1234
  • Liv1234
I already solved the problem, but I don't want to say what it is.
Liv1234
  • Liv1234
I think you should be converting 4 1/2 into a fraction.
anonymous
  • anonymous
o i hate fraction's
Liv1234
  • Liv1234
You multiply 4 by 2 and then add 1.
Liv1234
  • Liv1234
When you get the answer to that you put that number over 2.
Liv1234
  • Liv1234
Or to be exact, multiply the denominator by the number and then add that to the numerator.
anonymous
  • anonymous
so 4x2=8 and 8 plus 1 equals 9
Liv1234
  • Liv1234
Right!
skullpatrol
  • skullpatrol
yes, now put the 9 over 2
Liv1234
  • Liv1234
9/2 (:
Liv1234
  • Liv1234
That isn't your answer, but that's the fraction you need to help you solve the answer.
skullpatrol
  • skullpatrol
4 1/2 = 9/2
anonymous
  • anonymous
so i divid now 9 divid 45
Liv1234
  • Liv1234
No.
Liv1234
  • Liv1234
You are going to multiply.
anonymous
  • anonymous
o yyy
Liv1234
  • Liv1234
If I am not mistaken, it would be something like 9/2 * 45
Liv1234
  • Liv1234
\[9/2 * 45\]

Whenever you divide fractions, you end up multiplying them.
Liv1234
  • Liv1234
So, 45/1 * 2/9 (because I think you flip the reciprocal)
anonymous
  • anonymous
were did the 2 come from in 9/2
Liv1234
  • Liv1234
The mixed number.
skullpatrol
  • skullpatrol
|dw:1449970071286:dw|
Liv1234
  • Liv1234
And when you multiply that, what do you get?
Liv1234
  • Liv1234
\[45 * 2/9\]
Liv1234
  • 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
  • skullpatrol
yes
Liv1234
  • Liv1234
45/1 is the same thing as 45.
anonymous
  • anonymous
ok
Liv1234
  • Liv1234
If it was 1/45 it would be different, but it is 45/1 or 45 in this case.
anonymous
  • anonymous
so the answer is 10/1
Liv1234
  • Liv1234
10.
skullpatrol
  • skullpatrol
:D
anonymous
  • anonymous
right
Liv1234
  • Liv1234
Correct.
anonymous
  • anonymous
so the total answer is 10
Liv1234
  • Liv1234
Yes.
anonymous
  • anonymous
