Question
Identify the following as rational or irrational numbers. Give the decimal representation of rational numbers:
$\sqrt{1.44}$
$\sqrt{1.44}$
✓
Answer
We have,
$\sqrt{1.44}$
$=\sqrt{\Big(\frac{144}{100}\Big)}$
$=\frac{12}{10}$
$=1.2$
Every terminating decimal is a rational number, so 1.2 is a rational number. Its decimal representation is 1.2.
$\sqrt{1.44}$
$=\sqrt{\Big(\frac{144}{100}\Big)}$
$=\frac{12}{10}$
$=1.2$
Every terminating decimal is a rational number, so 1.2 is a rational number. Its decimal representation is 1.2.
