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 =
(48)/(99)

----------------------------------------------------------------------

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 =
(44)/(90) =
(22)/(45)

--------------------------------------------------------------------------

C

0.48 =
(48)/(100) =
(12)/(25) ← in simplest form
