Video to accompany the open textbook Math in Society (www.opentextboo.... Part of the Washington Open Course Library Math&107 course.

not understanding how you determine the remainder. I did the division, it doesnt line up

[@kriseetarhyna2152]

Thank you you helped me alot My teacher didn't even explain it in such an easy and simple way Thank u thank u thank u

[@CeCegurrrl258]

wish my math teacher explained math this well.

[@angledcoathanger]

Thank you very much, works perfectly.

[@mmaskkjoy7244]

what about dividing with a 7 to the power 4 number?

[@tawncunningham]

Thanks so much for the video!

how to convert 0.26222229 to base 7?

[@khangtonthat8764]

Am I dumb or is 4509 divided by 2401 is 1.8779...?????

[@cbm5655]

yea so this does not work for 13562 base ten or decimel to base seven. i beleive answer is 54353 but your route gave me errors or just 535000seven

[@ekornz.z]

13562 (ten) = 54353 (seven) This is what I got by doing same method.

Thanks

That's a clumsy method! It's easier to just continue doing integer division by 7 until you reach 0, and keeping track of all remainders. Put these together in reversed order and you get the result.

[@heran3326]

how do you find the remainder though? that part I cant seem to understand at all, and I've been using the method you mentioned

[@christianbrolin1482]

@@heran3326 4509 ÷ 7 = 644 R 1 644 ÷ 7 = 92 R 0 92 ÷ 7 = 13 R 1 13 ÷ 7 = 1 R 6 1 ÷ 7 = 0 R 1 The result is the remainder digits in reverse order, i.e, the digits after the Rs above, i.e. 16101. The remainder is what you get left after doing a long division without decimals. E.g. 17 ÷ 7 = 2 R x, where x = 17 - 2*7 = 17 - 14 = 3

@@christianbrolin1482 The division method shown here is clearly easier. Not sure why my teacher is telling us to do this
