Question

3. Convert the following decimals into rational numbers:

(b) 1.47 if bar is over 7​

Answer 1

they're already rational numbers since they're non-recurring decimals.

Answer 2

1.47 where seven is repeated

so its 1.4777777777777777777.............

multiply by 10

14.777777.........=10x

100x=147.777777...........

100x=147.777777.......

10x= 14.777777....

by elimination method

90x=133

x=133/90 and thats your fraction
