c) 27% de 900.
d) 55% de 300.
e) 98% de 450.​

Answer 1

30% 100

x 1.500

100x= 45.000

x= 45.000/ 100

x= 450

12% 100

x 120

100x= 1.440

x= 1.440/ 100

x= 14,4

27% 100

x 900

100x= 24.300

x= 24.300/ 100

x= 243

55% 100

x 300

100x= 16.500

x= 16.500/ 100

x= 165

98% 100

x 450

100x= 44.100

x= 44.100/ 100

x= 441

Answer 2

Olá...

2) Calcule:

a) 30% de 1500.

100x = 30.1500

100x = 45 000

x = 45 000/100

x = 450

b) 12% de 120.

100x = 12.120

100x = 1440

x = 1440/100

x = 14,4

c) 27% de 900.

100x = 27.900

100x = 24300

x = 24300/100

x = 243

d) 55% de 300.

100x = 55.300

100x = 16500

x = 16500/100

x = 165

e) 98% de 450.​

100x = 98.450

100x = 44100

x = 44100/100

x = 441

Bons estudos.
