Answer 1

Rational number with denominator 4 from the given set of numbers in their lowest form are listed below

$\frac{64}{16}=\frac{16}{4}$

$\frac{36}{(-12)}=\frac{12}{(-4)}$

$\frac{5}{(-4)}$

$\frac{140}{28}=\frac{20}{4}$

Hence, $\frac{16}{4},\frac{12}{(-4)},\frac{5}{(-4)},\frac{20}{4}$ can be written as a rational number with denominator 4 in their lowest form
