Question

change the following decimal number in p/q form.
Q. )8.38 bar

please tell sir how to solve it
​

Answer 1

Answer:

if bar is on 38 then

x=8.38... --------eq1

multiply by 100 in both sides

100x =838.38......eq2

now Subtract eq1 by eq2

100x-x =838.38...- 8.38..

99x = 830

x=830/99

OR if bar is only on 8 then

x = 8.38..

multiply by 10 on both sides

10x = 83.8..-------eq1

now multiple by 100 on both sides

100x = 838.8....----eq2

now Subtract eq1 by eq2

100x-10x =838.8...-83.888

90x = 755

x = 755/90

Hope this will help
