A jewelry maker has 51 inches of chain. She wants to cut the chain into 9 equal parts. How long will each part be?
Hey are there any answer choices?
yeah hold up
4 2/9 5 6/9 6 2/5 7 3/9
Ok first off, what's 51 divided by 9?
Need a guide? Because it does go into decimals.
5 2/3
Ah close, let's go through it.
ok
Lets solve it like this : |dw:1613488106808:dw|
9 goes into 5 how many times?
0?
Yep. So this means that. you put a zero at the top, one sec.
|dw:1613488276203:dw|
im not god will division
-w-
it's ok lol
I'll skip a few steps since it doesn't work for this certain quesiton, but
It basically turns into this: |dw:1613488382217:dw|
Next step you bring down the 1 with the 5 |dw:1613488436430:dw|
mhm
How many times can 9 go into 51?
9+9+9+9+9 9-18-27-36-45
There are 5 times 9 in 51?
yes.
since 9 x 6 would be more then 51 you have to use number 45 which is 9 x 5
It would now look like this : |dw:1613488653955:dw|
So whats 51 minus 45?
5!
5 remainder 6! since subtracting 51 - 45 = 6
|dw:1613488799144:dw|
now that we know the division answer what seems like the closest answer now?
yeah I see lol, but what do you think the answer is now? 4 2/9 5 6/9 6 2/5 7 3/9 (5 remainder 6 was the answer we just got)
Ok, if you use a calculator and divide 51 by 9 you get the answer 5.66**** (keeps going) what seems close the same in fractions? Wouldn't you think 5 6/9 is close to 5 remainder 6? The same goes for 5.66****
To sum it up, the correct answer is 5 6/9. Do you get how I got there though?
yeah a lil
thx tho
