Question

0. 72,2 is having bar express in p/q form

Answer 1

0.72 (bar over 2)
let x = 0.7222. — 1
on multiplying 10 to eq. 1
10x = 0.7222 * 10
10x = 7.2222. — 2
on multiplying 100 to eq. 1
100x = 0.7222 * 100
100x = 72.2222 — 3
on subtracting eq. 2 from eq. 3
100x - 10x = 72.2222 - 7.2222
90x = 65
x = 65/90 = 13/18
therefore 0.7222 can be represented as 13/18
