Express 0·4393939... as a fraction in its lowest term

Step-by-step explanation:

We require 2 equations with the repeating digits 39 placed after the decimal point.

1000x = 439.3939... → (2)

Subtract (1) from (2) eliminating the repeating digits

990x = 435 ( divide both sides by 990 )

x = = ← in simplest form
