Answer:
see explanation
Explanation:
We require 2 equations with the repeating decimal placed after the decimal point.
A
Note that 48 with a bar over it indicates 48 is repeated, that is
0.484848........
let x = 0.48.... → (1) multiply both sides by 100
100x = 48.48..... → (2)
Subtract (1) from (2) to eliminate the repeating decimal
99x = 48 ( divide both sides by 99 )
x =
----------------------------------------------------------------------
B
note that this time we have 0.4888888......
let x = 0.488.. ( multiply both sides by 10, then 100
10x = 4.8888... → (1)
100x = 48.8888.... → (2)
Subtract (1 ) from (2) to eliminate the repeating decimal
90x = 44 ( divide both sides by 90 )
x =
=
