Question

$\frac{1.2\times 1.2+1.2\times 0.3+0.3\times 0.3}{1.2\times 1.2\times 1.2-0.3\times 0.3\times 0.3}=\frac{m}{1.8},Findm$.Write upto 3 decimal

Answer 1

$\left(\frac{1.44+0.36+0.9}{1.728-0.027}\right)=\left(\frac{m}{1.8}\right)\left(\frac{2.7}{1.701}\right)=\left(\frac{m}{1.8}\right)\therefore m=\left(\frac{2.7\times 1.8}{1.701}\right)=2.857\left(approx\right)$
