Question

express 5.2 in the form of p/q , where p and q are integers and q is not equal to 0

Answer 1

Answer- Let x= 5.2 bar

x= 5.22_ _ _ --(1)

Multiply by 10 on both sides

10x= 52.22_ _ _--(2)

(2)-(1)

9x= 47

x= 47/99

Therefore, x=5.2 bar = 47/99 (p/q)

Answer 2

HEY!!

____________________________

✴5.2 bar

☞Let x = 5.2222222... (EQUATION 1)

☞Multiplying both sides by 10

☞10x = 52.2222222... (EQUATION 2)

☞Subract equation 1 from equation 2

☞9x = 47

☞x = 47/9
