1. yakabush1 Group Title

i got 480/80

2. theEric Group Title

Is this $2 \times \frac{3}{8}$?

3. yakabush1 Group Title

yes

4. yakabush1 Group Title

helooooooooo

5. yakabush1 Group Title

1

6. BifocalComb Group Title

you have to multiply only the numerator by the three

7. BifocalComb Group Title

oops i meant two

8. theEric Group Title

Just remember that fractions are really the amount on top (numerator) divided by the amount on bottom (denominator). One way to look at it is to turn the fraction $\frac{3}{8}$ into$3\div8$, so you have $2\times3\div8$Then solve the multiplications and divisions separately$(2\times3)\div(8)=(6)\div(8)$and then make it look like a fraction again:$\frac{6}{8}$. That can be simplified, though. Or, look at the "2" like this:$\frac{2}{1}$, and multiply numerators together and denominators together. It's the same thing. Then$\frac{2}{1}\times\frac{3}{8}=\frac{2*3}{1*8}=\frac{6}{8}$.

Those are two ways to think about multiplying fractions!

10. theEric Group Title

Sorry I took so long!

11. yakabush1 Group Title

ok thanks

12. yakabush1 Group Title

can u help me in one more

13. theEric Group Title

Can you simplify it? Divide top and bottom by 2! Some teachers require simplification...

14. theEric Group Title

Possibly! I have to go soon! You post it, and I'll see if I can help!

15. yakabush1 Group Title

1 1/2 divided by 3

16. theEric Group Title

If it's very similar, I hope that you can do it on your own, or we can do it together!

17. theEric Group Title

So,$1\frac{1}{2}\div3$

18. yakabush1 Group Title

i got 1 2/20

19. theEric Group Title

That is different!

20. theEric Group Title

That's not quite right, but we'll get there! $1\frac{1}{2}=1+\frac{1}{2}$, right?

21. yakabush1 Group Title

yeah

22. theEric Group Title

and 1, as a fraction, is any number over itself, like$1=\frac{2}{2}$right? Then you can look at $1+\frac{1}{2}$like$\frac{2}{2}+\frac{1}{2}=\frac{3}{2}$

23. theEric Group Title

$1\frac{1}{2}=\frac{3}{2}$

24. yakabush1 Group Title

thanks men

25. theEric Group Title

$=3\div2$

26. theEric Group Title

That's just the fraction... You still have to divide by 3.

27. yakabush1 Group Title

1.5

28. theEric Group Title

$\frac{3}{2}=3\div2$ I did that again.. Similar to what we did before! Fraction to division... Really the same thing. Anyway, $1\frac{1}{2}\div3=\frac{3}{2}\div3=3\div2\div3=3\div3\div2=1\div2$ See what I did there? And, if you need the fraction, I trust you can find it!

29. theEric Group Title

It's just lucky that $3\div3=1$, because it made our problem easier! :)

30. BifocalComb Group Title

Eric if you want I'll take over from here if you have to go..

31. theEric Group Title

Thanks! I trust you can help with this question and any others! :) I do have to get going. Take care, all!
