Answer 2

➤ Answer :-

$\dashrightarrow \sf20:45 = \frac{20}{45}$

$\dashrightarrow \sf \cancel \frac{20}{45} = \frac{4}{9}$

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

$\dashrightarrow \sf8:15 = \frac{8}{15}$

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Now,

$\dashrightarrow \sf \frac{4}{9} \: \boxed{?} \: \frac{8}{15}$

LCM of 9 and 15 is 145.

$\dashrightarrow \sf \frac{4 \times 15}{9 \times 15} \: \boxed{?} \: \frac{8 \times 9}{15 \times 9}$

$\dashrightarrow \sf \frac{60}{145} \: \boxed{ \cancel= } \: \frac{72}{145}$

$\Huge\therefore$They both are not equal.
