Question

Write 3.8bar in the form of p/q

Answer 1

Let x = 3.8888....... then,        ----------------------(1)

10x = 38.888.........                  ---------------------(2)

Subtracting 1 from 2 equations, we get

10x - x = 38.888.... - 3.8888......

9x = 35

x = 35 / 9

Answer 2

Step-by-step explanation:

x = 3.888... => eq 1

(mutiply 10 on both sides )

10x = 10 * 38.888...

10x = 38.888 => eq 2

( subtracting eq1 from eq2 )

10x - x = 38.888 - 3.888

9x = 35

x = 35/9

3.88... can be expressed in p/q form as 35/9
