71% de RS 2.500,00

350% de RS 5.000,00

Answer 1

Explicação passo-a-passo:

a) 85% de 4000

100% ————— 4000

85% —————— x

100x = 85.4000

100x = 340000

x = 340000/100

x = 3400

b) 71% de 2500

100% ————— 2500

71% —————— x

100x = 71.2500

100x = 177500

x = 177500/100

x = 1775

c) 350% de 5000

100% ————— 5000

350% ————— x

100x = 350.5000

100x = 1750000

x = 1750000/100

x = 17500
