Question

Write the following rational number in `p/q` form.

`15.bar89`

Sum
Advertisements

Solution

Let x = `15.bar89`    ...(1)

Multiplying both sides by 100, we get

100x = `1589.bar89`   ...(2)

Subtracting (1) from (2), we get

∴ 100x − x = `1589.bar89 − 15.bar89`

∴ 99x = 1574

`therefore x =  1574/99 `

So, `15.bar89 = 1574/99`
