alloo!

1. 0,3 × 1 ⅖ - 18,6

Pake cara yhh!!

$0,3 \times 1 \frac{2}{5} - 18,6 \\ = \frac{3}{10} \times \frac{7}{5} - \frac{186}{10} \\ = \frac{21}{50} - \frac{186}{10} \\ = \frac{21}{50} - \frac{930}{50} \\ = - \frac{909}{50}$

0,3 × 1 ⅖ - 18,6

$= \frac{3}{10} \times \frac{(5 \times 1 + 2)}{5} - \frac{186}{10} \\ \\ = \frac{3}{10} \times \frac{(5 + 1)}{5} - \frac{186}{10} \\ \\ = \frac{3}{10} \times \frac{7}{5} - \frac{186}{10} \\ \\ = \frac{(3 \times 7)}{(10 \times 5)} - \frac{186}{10} \\ \\ = \frac{21}{50} - \frac{186}{10} \\ \\ \sf{ \green{= \frac{ - 165}{38} }}$
