Question

Necesito ayuda en mate y no entiendo :(​

Answer 1

$310 \times \frac{9}{100} = \frac{2790}{100} = 27.90$

Se multiplica y se divide en 100

$3600 \times \frac{12}{100} = 36 \times 12 = 432$

$20 \times \frac{25}{100} = \frac{500}{100} = 5$

$2000 \times \frac{46}{100} = 20 \times 46 = 920$

$8500 \times \frac{55}{100} = 85 \times55 = 4675$

$30 \times \frac{60}{100} = \frac{1800}{100} = 18$
