Answer 1

$\huge\mathfrak\red {｡｡ϙᴜᴇSᴛɪᴏɴ ｡｡ }$

which of the following is a rational number

$1. \sqrt{5 }$

$2.\pi$

$3.0.101001000......$

$4.0.853853$

$\huge\mathfrak\blue {ᴀɴsᴡᴇʀ }$

⟹ $\sqrt{5} = 2.23$

→$\pi = \frac{22}{3} \: \: or \: \: 13.5$

⟹ $3.0101001000 = \frac{3010100100}{100000000000}$

⟹ $40.853853 = \frac{40853853}{10000000}$
