Simplify: $(2\frac{1}{4}\times 1.6) + (1\frac{1}{3} \div 0.4)$

Convert mixed numbers:

$2\frac{1}{4} = \frac{9}{4}$
$1\frac{1}{3} = \frac{4}{3}$

Convert decimals:

$1.6 = \frac{8}{5}$
$0.4 = \frac{2}{5}$

First term:

$\frac{9}{4} \times \frac{8}{5} = \frac{72}{20} = 3.6$

Second term:

$\frac{4}{3} \div \frac{2}{5} = \frac{4}{3} \times \frac{5}{2} = \frac{20}{6} = \frac{10}{3}$

$\frac{10}{3} = 3.33$

Add them:
3.6 + 3.33 = 6.93
