Question

Cem bombons custaram R$37,00. Qual é o preço de 150 bombons? E de 210? Quantos bombons se pode comprar com R$95,50?

Answer 1

$100 > > > 37 \\ 150 > > > > x$
$100x = 150 \times 37$
$100x = 5550$
$5550 \div 100 = 55.50reais$
$150 > > > > 55.5 \\ 210 > > > > > x$
$150x = 210 \times 55.5$
$150x = 11.655$
$x = 11655 \div 150 = 77.70 \: reais$
$100 \div 37 = 2.70 \: cada$
$95.50 \div 2.70 = 35 \:$
