Question

convert 0.143 into vulgar fraction if the bar is at 43​

Answer 1

Answer:

71/495

Step-by-step explanation:

(143-1)/(1000-10)

=142/990

= 71/495

for similar problems, you can use the below given method to find the fraction

1. write number ignoring decimal and bar ( in the instant case it is 143)

2. write number ignoring decimal but excluding digits on which there is bar (in the instant case only digit 1 has no bar)

3. write 1 followed by number of as much zero as there are total digits after decimal (in this case there are three digits after decimal so 1000)

4. write 1 followed by as much zero as there are digits after decimal but without bar (in this case, there is only one digit 1 after decimal which has no bar so 10)

now,

the required fraction is

(1-2)/(3-4)

Answer 2

Answer : 14341.5657/990

Step-by-step explanation:

x=0.143

Multiply both sides by 10( since the number of digit without bar is 1)

__

10x = 1.43

10x = 1.4343------------ (I)

10 X 100x = 1.43---- X 100 ( since number of digit having bar is 2)

1000x =14343------- (ii)

subtracting (I) from (ii)

1000x - 10x = 14343 - 1.4343

990x = 14341.5657

x = 14341.5657/990
