Question

5 Find a rational and an irrational number between the following: (a) ‐1/3 and 2/5 (b) root 3 and root 5
​

Answer 1

Step-by-step explanation:

$\rm(a) \frac{ - 1}{3} \: \: and \: \: \frac{2}{5}$

Take LCM of 3 and 5

$\frac{ - 1}{15} , \frac{2}{15}$

$\sf So \: rational \: number \: between \frac{ - 1}{15} \: and \: \frac{2}{15} \: is : -$

$\frac{0}{15} , \frac{1}{15}$

$b) \: \sqrt{ 3} \: and \: \sqrt{5}$

$\sqrt{ \sqrt{3} \times \sqrt{5} }$

$\sqrt{ \sqrt{15} }$

${(15})^{ \frac{1}{4} }$

$=1.97$
