Question

Express 3.121212 in p/q form​

Answer 1

Answer:

_

3.12

X=3.12 —1

Multiplying 100 both sides

X× 100=3.12×100

100X=312.12

WE CAN ALSO WRITE THAT

312.12=309+3.12

From this

100X=309+3.12

From 1=x=3.12

So,100x=309+x

100x-x=309

99x=309

X=309/99

X=103/99

Therefore we can write 3.121212 in the p/q form=

103/99
