Answer 2

$Product \:of \: \frac{27}{28} \times \frac{20}{21} \\= \frac{ 27\times 20}{28\times 21}\\= \frac{3\times 3\times 3 \times 2\times 2\times 5 }{2\times 2 \times 7 \times 3\times 7 }$

/* After cancellation,we get */

$= \frac{3\times 3 \times 5}{7 \times 7 } \\= \frac{45}{49}$

Therefore.,

$\red{ Product \:of \: \frac{27}{28} \times \frac{20}{21}} \green {= \frac{45}{49} }$
