6) Calcule as porcentagens correspondentes:
a) 40% de 48 m
b) 38% de 200 Kg
c) 6% de 50 telhas


vandogarcia32: a) 19,2 m
b) 76 kg
c) 3 Telhas
lucasluluxa: humilde dms
vandogarcia32: a) 48 / 100 = 0,48
0,48 * 40 = 19,2

b) 200/100 = 2
2 * 38 = 76

c) 50/100 = 0,5
0,5 * 6 = 3

Resposta:

A)

40\% \:  \:  \: de \: 48 \\  \frac{100}{40}  =  \frac{48}{x}  \\ 100x = 1.920 \\ x =  \frac{1.920}{100}  =  \\ x = 19.2

B)

38\% \:  \:  \: de \:  \:  \: 200 \\  \frac{100}{38}  =  \frac{200}{x}  \\ 100x = 7.600 \\ x =  \frac{7.600}{100}  \\ x = 76

C)

6\% \:  \:  \: de \: 50 \\  \frac{100}{6}  =  \frac{50}{x}  \\ 100x = 300 \\ x =  \frac{300}{100}  \\ x = 3

Espero ter ajudado em algo...
