$7.47$ $7.47$

$4.15 \times 1.8$ $4.15 xx 1.8$

Split them into parts

$\Rightarrow (4 + 0.15) \times (1 + 0.8)$ $=> (4+0.15)xx(1+0.8)$

Now multiply individually

$\Rightarrow 4 (1 + 0.8) + 0.15 (1 + 0.8)$ $=> 4(1+0.8) + 0.15(1+0.8)$

$\Rightarrow 4 + 3.2 + 0.15 + 0.12$ $=> 4 + 3.2 + 0.15 + 0.12$

$\Rightarrow 7.2 + 0.27$ $=> 7.2+0.27$

$\Rightarrow 7.47$ $=> 7.47$
