Question

express the following number in the form ofp/q where p and q are both integer and q is not equal to zero :- 0.7​

Answer 1

let

x=0.7........(1)

multiply 10 both sides..

10x=7........(2)

subtracting eq. (1) from (2) ..

10x-x=7-0.7

9x=6.3

x=6.3/9

x=63/90

x=21/30

x=7/10

so number is 7/10
