Question

please answer it step by step​

Answer 1

Answer:

okay

Step-by-step explanation:

1). let 0.4 bar be x

so

x = 0.44444444.... (1)

multiply 10 on both sides

10x = 4.44444444.... (2)

eq (2) - eq (1)

9x = 4

x = 4/9

so form is rational will be 4/9

and anything else

just try with yourself if you don't understand then ask me I'll tell you

Answer 2

Answer:

Q1 0.4444...

Step-by-step explanation:

let x =0.444... eq1

multiplying both side by 10

10x=4.444... eq2

subtracting equation 1 from equation 2

9x=4

x=4/9 ans

Q2 0.373737...

let x=0.373737... eq 1

multiplying both side by 100

100x=37.373737... eq 2

subtracting equation 1 from eq 2

99x=37

x=37/99 ans

Q3 0.575757....

let x =0.575757... eq1

multiplying both side by 100

100x=57.575757... eq2

subtract eq1 from eq2

99x=57

x=57/99 ans

Q4 0.621621621...

let x=0.621621621... eq1

multiplying both side by 1000

1000x=621.621621621... eq2

subtract eq1 from eq2

999x=621

x=

621/999 ans

Q5 125.333...

let x=125.333... eq1

multiplying both side by 10

10x=1253.333... eq2

subtract eq1 from eq2

9x=1128

x=1128/9 ans

Q6 4.777...

let x=4.777... eq1

multiplying both side by 10

10x=47.777... eq2

subtract eq1 from eq2

9x=43

x=43/9 ans

Q7 0.4777...

let x=0.4777... eq1

multiplying both side by 10

10x=4.7777... eq2

subtract

9x=4.3 ans

May be Q5and 7 is wrong.
