Question

express 125.3(bar is on 3) in the form of p/q

Answer 1

Heya !!!



125.3 ( bar on 3)



Let X = 125.3



Then X = 125.33 ----(1)



Multiply equation (1) by 10 we get,



10X = 1253.33 ------(2)



Subtract equation (1) from equation (2) we get,



10X = 1253.33


X = 125.33
___________



9X = 1128



X = 1128/9


X = 376/3



Hence,


125.3 ( bar on 3) is in the form of 376/3 which is in the form of P/Q


HOPE IT WILL HELP YOU...... :-)

Answer 2

GIven question=125.3 bar on three. we can write it as 125.3333333.. and so on. first, put x=125.33333.. as we can see that bar is upon one digit (3). So, multiply 10 to both sides to avoid bar. so now 10x=125.333..×10. from this , we get 10x=1253.333 now we can write it as 10x=1128+125.333 from this we get 10x=1128+x. so, 10x-x= 1128 , 9x=1128, x=1128/9,=376/3. From this we can express 125 . 3(bar on 3) in dorm of p/q as 376/3 where p and q are integers and q is not equals to 0.
