Question

represent 0.93bar in rational form

Answer 1

Hey mate
Here's your answer

[ remember 0.93 bar on 3 = 0.9333333.... ]

Let x = 0.933333....

10x = 10 × 0.933333......
= 9.333333....

100x = 100 × 0.9333332....
= 93.333333...…

So here as we saw in 100x and 10x the digits after the decimal point [.] are same ie. 333...

So if we will subtract them then we will be able to get a whole number.

100x - 10x = 93.33333..... - 9.333333....
=> 90x = 84
=> x = 84/90 = 42/45

Now since 42/45 is in the rational form. That is your answer.


Hope this helps ☺!
