Question

express 0.631 bar in p/q form

Answer 1

x=0.631631.... Eqn1
1000x=631.631631..... Eqn2

Subtracting eqn1 from eqn2,
1000x-x=631.631....-0.631.....
999x=631
x=631/999

Answer 2

Step-by-step explanation:

2.5 let x =2.5

or,x=2.5 (1)

multiplying equations (1) by 10, we get

10x=2.5 (2)

subtracting equations (1) from equations (2)

10x=25.5

x= 2.5

=9x=23
