Oh, dude, you're hitting me with the math questions now? Alright, so the base 10 representation of 142 base 5 is... drum roll... 47! Yeah, it's like converting currencies, but with numbers. So, in base 5, 142 is like saying 1x5^2 + 4x5^1 + 2x5^0, which equals 47 in base 10. Cool, right?

this was a wrong answer.
divide = 10 with 2 remainder, make the remainder into a fraction 2/10 and reduce 142/10 = 14 1/5
14.2 = 142/10 = 71/5

In base 11 vs In base 10 10 = 11 20 = 22 30 = 33 So, it is simply dividing whatever value in base 11 by 10 then multiplying it back by 11, but digit by digit. Example, 45 in base 11: 45 = 40 + 5 (still true) = 40/10*11 + 5 (leave the 5 untouched) = 44 + 5 = 49 (in base 10)
