# Thread: lol something I found

1. ## lol something I found

I was trying to do the math problem 7/10 x 2/3 x 2/5 and then after failing multiple times, I found this:

0.18666666666 x 5.35714285735 = 1

search the equation up if you don’t believe me. 2. ## i dont get how special this is

isn't it just (some obscure number) * (some other obscure number) = 1 and it's not hard to figure out. you just divide 1 by (some obscure number) to get (some other obscure number). 3. ## (to make math easier for you: do 7*2*2/10*3*5=28/150=14/75)

14/75 * 75/14 = 1050/1050 = 1 4. ## Did you know that

0/0 = maths error?

Now you do! 5. ##  Originally Posted by Caine Did you know that

While I suck a lot at math, I understand this lol 6. ## fun fact
111111111 x 111111111 = 12345678987654321 7. ##  Originally Posted by Caine Did you know that

I didn’t divide it because I’m “smart” that way.  Originally Posted by DynPlaysGT fun fact

Same, I’m with you, because i’m extremely slow at math 8. ## You didn't really need to turn it into a decimal fraction, doing it without a calculator that turns normal fractions into decimals would have been easier. #### Posting Permissions
