Question
Write the following as rational numbers in their standard forms.
115÷207
115÷207
✓
Answer
Given,
$\because \quad 115=5 \times 23$
$\Rightarrow \quad 207=3 \times 23 \times 3$
$\therefore$ HCF of 115 and 207= 23
On dividing numerator and denominator by their HCF, we get
$\frac{115 \div 23}{207 \div 23}=\frac{5}{9}$
$\because \quad 115=5 \times 23$
$\Rightarrow \quad 207=3 \times 23 \times 3$
$\therefore$ HCF of 115 and 207= 23
On dividing numerator and denominator by their HCF, we get
$\frac{115 \div 23}{207 \div 23}=\frac{5}{9}$
