Question

Express 2.218 (bar only on 18)in the form of p by q where p and q are integers and q is not equal to 0

Answer 1

Hay!!

Dear friend -

_______________________________

We let 2.2181818 = x

So,

22.1818 = 10x

And 2218.1818 = 1000x

Now we subtract it

10x form 1000x = 2218.1818- 22.1818

990x = 2196

X= 2196/990

I hope it's help you

Answer 2

Heya !!!

2.218 ( bar on 18)

Let X = 2.218

Then X = 2.2181818 ---------(1)

Multiply equation (1) by 10 we get,

10X = 22.181818 -------------(2)

Again multiply equation (2) by 100 we get,

1000X = 2218.181818 ---------(3)

Subtract equation (1) from equation (2) we get,

1000X = 2218.181818
10 X = 22.181818
_________________

990X = 2196

X = 2196/990 =122/55

Hence,

2.218 ( bar on 18) is in the form of 244/55 which is in the form of P/Q.

HOPE IT WILL HELP YOU...... :-)
