If
, then there is some integer
such that
. Because
, it follows that
, which means there is some integer
such that
, which is equivalent to the statement that
.
An= a1r^(n-1)
a7= 27(1/3)^(7-1)
= 27(1/3)^6
= (1/3)^(-3) * (1/3)^6
= (1/3)^(-3+6)
= (1/3)^3
= 1/27 #
If you would like to know how many sixths are in 4, you can calculate this using the following steps:
n ... the number of sixths
n * 1/6 = 4
n = 4 * 6
n = 24
The correct result would be: 24 sixths are in 4.
