Question

Change the recurring decimal 0.4 to a fraction.

Answer 1

Answer:

0.4 =0.4/1 ×10/10

=4/10

Answer 2

Answer:

0.4 = 4/9

Step-by-step explanation:

Let x = 0.4 --------------- 1

10x = 4.4 ( here only one digit in the decimal part is repeating, so we multiply by 10 ) ------------- 2

Subtracting ( 1 ) from ( 2 ) we get,

10x - x = 4.4 - 0.4

9x = 4

x = $\frac{4}{9}$
