Question

maths part 1 lsn no 2
Write in p/q form of 0.4 step by step with sentences​

Answer 1

Answer:

let 0.4 bar be x

so

x = 0.44444444

multiply 10 on both sides

10x = 4.44444444

eq (2) - eq (1)

9x = 4

x = 4/9

so form is rational will be 4/9

Answer 2

hey cu-tie pi-e

let 0.4 bar be x

so

x = 0.444-4-4444....-. (1)

mu-ltiply 10+ on +bo+th si-des

10-x = 4.44-444444.... (2)

eq (2) - eq (1)

9-x = 4

x = 4/9

so for-m is rati-onal will be 4/9
