Question

Express 2.23 bar is as a rational number in the simplest form

Answer 1

Answer:

221/99

Step-by-step explanation:

Let 2.23 bar = a ----------------- eq. 1

Multiply Both Sides by 100:

2.23 bar x 100 = a x 100

=> 223.23 bar = 100a ------------------ eq. 2

Now, Subtract eq. 1 from eq. 2:

223.23 bar - 2.23 bar = 100a - a

221 = 99a

99a = 221

=> a = 221/99

Ans:- 2.23 bar as a Rational Number in its simplest form = 221/99

Answer 2

Answer:

2.23 Bar has a rational number in it's simplest form =221/99

Step-by-step explanation:

=> let 2.23 bar=a×100…..……….........eq-1

=> multiply both sides by 100

=> 223 .23 bae =100 a.....................eq-2

=> Now,subtract eq1 from eq2

=> 223.23 bar-2.23 bar =100a-a

=> 221=99a

=> 99a=221

=> a=221/99
