$5. { 63 } \ \times 11$ is equal to

  1. $62$
  2. $83.\overline { 93 } $

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

$5.\overline { 63 } $
$=5.636363...$
Let $x=5.6363$  (i)
$\therefore 100x=563.6363$  (ii)
Subtracting (i) from (ii) we get,
$=>99x=558$
$=>x=\dfrac{558}{99}$
Now,$5.\overline { 63 }\times 11$
$=>\frac{558}{99}\times 11$
$=>62$
