Question

Express 0.47777....in the form of a rational number.

Answer 1

Answer:

answer is 43/80

Step-by-step explanation:

let x=0.47 bar on 7(1)

multiply both sides by 10

10 x = 4.7 bar

multiply both side by 10

100 x =47.7 bar(2)

subtract (2) from (1), we get

100x- 10 x=47.7 bar-4.7 bar

90x=43

x=43/90
