Question

convert the following number in the form of p/q
0. 5 bar on 23
0. bar on 523
0.bar on 7
0.bar on 89​

Answer 1

Step-by-step explanation:

let x= 0. bar on 7 (1)

x=0.7777...

multiply 10 on both sides

x×10=0. bar on 7 ×10

10x=7.7777.. (2)

subtract (1) from (2)

10x -x = 7.777... - 0.7777...

9x=7

x=7/9
