3.15 the vinculum is above the 5,so the # is 3.15555...
let x = 0 .15555...
thus
10x = 10*0.1555... / . 10 because there is only one
repeating number 5,if there is two
multiply by 100, 3 multiply by 1000
10x = 1.5555...
- x = -0.1555... / x = 0.1555...
9x = 1.4000
x = 1.4/9 = 14/90
thus the # is 3 14/90
