Question

write 3.5<72>bar in the form of p/q

Answer 1

hey mate! here's your answer
_____________________

let x = 3.5727272....

so,

10x = 10 × 3.5727272....

=> 10x = 35.727272...

then,

10x × 100 = 35.727272... × 100

=> 1000x = 3572.727272...

now,

1000x - 10x = 3572.727272... - 35.727272...

=> 990x = 3537

=> x = $\frac{3537}{990}$

we can simplify it more:-

=> x = $\frac{393}{110}$ (Answer)
