g) 90% de 10000
h) 15% de 568
i) 25% de 600
j) 35 % de 700
k) 55% de 650
l) 65% de 430
m) 13% de 395
n) 14% de 700
o) 47% de 5000
Respostas
Resposta:
f) 8.000 --- 100%
x --- 80%
100x = 640.000
x = 640.000 : 100
x = 6.400
_________________
g) 10.000 --- 100%
x --- 90%
100x = 900.000
x = 900.000 : 100
x = 9.000
_________________
h) 568 --- 100%
x --- 15%
100x = 8.520
x = 8.520 : 100
x = 85.2
_________________
i) 600 --- 100%
x --- 25%
100x = 15.000
x = 15.000 : 100
x = 150
_________________
j) 700 --- 100%
x --- 35%
100x = 24.500
x = 24.500 : 100
x = 245
_________________
k) 650 --- 100%
x --- 55%
100x = 35.750
x = 35.750 : 100
x = 357.50
_________________
L) 430 --- 100%
x --- 65%
100x = 27.950
x = 27.950 : 100
x = 279.5
_________________
m) 395 --- 100%
x --- 13%
100x = 5.135
x = 5.135 : 100
x = 51.35
Boa sorte e bons estudos!
