anonymous one year ago Penny uses 3/4 yard of fabric for each pillow she makes. how many pillow can she make using 6 yards of fabric? Do I turn 6 into a fraction, use the reciprocal and cross multiply?

1. anonymous

first off, there is no such thing as "cross multiply"

2. anonymous

In my school they use cross multiplying as simplify im only in 6th grade

3. anonymous

divie $$6$$ by $$\frac{2}{4}$$ which is the same as multiplying $$6$$ times $$\frac{4}{3}$$

4. anonymous

tell your teacher satellite73 said there is no such mathematical operation as "cross multiply" and to remove that from his or her vocabulary

5. anonymous

answer is 7 and 1/2 pillow cases

6. anonymous

I sure will!

7. anonymous

in any case your job is to compute $\large 6\div \frac{3}{4}=6\times \frac{4}{3}$

8. anonymous

its called cross simplifying

9. anonymous

cancel first, multiply last the answer is not seven and a half

10. anonymous

there is not such thing as "cross simplifying" either or "simplify" for that matter

11. anonymous

Honestly rounding that was mental math and it is close to the answer and it is cross products

12. anonymous

I got 8 as an answer, is it correct?

13. anonymous

yes

14. anonymous

three goes in to six two times, two times four is eight

15. anonymous

Ever heard of cross products...

16. anonymous

I simplified both fractions

17. anonymous

yes of course for vectors

18. anonymous

Ps i might sound dum because im really really really tired

19. anonymous

6/1 / 3/4 = 6/1 * 4/3 = 24/3 = 8 so 8 pillowcases

20. anonymous

And cross multiplying is a term used in Core Connections/ CPM 6th and 7th grade math.

21. anonymous

And i am not in a mental state of making right choices because I just took a shower which "Woke" me up and I can't fall asleep

22. anonymous

ima go help people with science :)#Science is the best!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

23. anonymous

It is basically what i did above just taken out of fraction form: |dw:1444099440255:dw|

Sorry for the weird scribbles. Although you wouldn't really use cross multplication here because there are no variables in the fractions.
