For each part of this problem, convert the fraction to a "decimal" in the specified base. (a) Convert the fraction 1/2 to base 3.

(b) Convert the fraction 1/7 to base 8.

(c) Convert the fraction 1/(b-1) to base b.

I already have the solutions to parts a and b, but I included them for context. It would be great if someone helped explain c. I know the answer to c, but not why and how it's proven. It'd be great if someone explained that. Thank you!

step-by-step explanation:

3/10 times, the 5 year old will get a tablet. 5/10 times, the 13 yer old will get a tablet. multiply both fractions to get 15/100 times, both would have a tablet.

hello from mrbilldoesmath!

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice
