Question

Express 3.127(7 bar) into p/q form​

Answer 1

Answer:

hope this helps....

Step-by-step explanation:

let x = 3.12777777..... equation (1)

here, the periodicity is 1

so, we multiply with 10 both sides.

10 × x = 10 × 3.1277777...

10x = 31.277777... equation (2)

subtract the equation 1 from 2....

10x = 31.277777....

x = 3.127777.....

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

9x = 28.15

‐-----‐---------------------------------

x = 28.15/9

x = 563/180
