A)

$\dfrac{100}{100} =\dfrac{30}{X} \\ 100X = 100 * 30 \\ 100X = 3000 \\ X =\dfrac{3000}{100} \\ X = 30$


Resposta : 30 dias


B)

$\dfrac{100}{50} =\dfrac{60}{X} \\ 100X = 50*60 \\ 100X = 3000 \\ X =\dfrac{3000}{100} \\ X = 30$

Resposta : 30 alunos

C)

$\dfrac{100}{25} =\dfrac{80}{X} \\ 100X = 25 * 80 \\ 100X = 2000 \\ X =\dfrac{2000}{100} \\ X = 20$

Resposta : 20 laranjas


D)

$\dfrac{100}{200} =\dfrac{120}{X} \\ 100X = 200 * 120 \\ 100X = 24000 \\ X =\dfrac{24000}{100} \\ X = 240$
