Answer 1

Olá...

a) 96% de R$79,90

100x = 96.79,90

100x = 7670,4

x = 7584/100

x = 76,704

b) 75% de R$ 90,00

100x = 75.90

100x = 6750

x = 6750/100

x = 67,5

c) 82% de R$8,00

100x = 82.8

100x = 656

x = 656/100

x = 6,56

d) 13% de R$7,36

100x = 13.7,36

100x = 95,68

x = 95,68/100

x = 0,9568

e) 15% de 60

100x = 15.60

100x = 900

x = 900/100

x = 9

f) 23% de 120

100x = 23.120

100x = 2760

x = 2760/100

x = 27,6

g) 100% de 4000

100x = 100.4 000

100x = 400 000

x = 400 000/100

x = 4 000

h) 45% de 3986

100x = 45.3986

100x = 179370

x = 179370/100

x = 1793,7

i) 98% de 698

100x = 98.698

100x = 68404

x = 68404/100

x = 684,04

m) 89%  de 7094​

100x = 89.7094

100x = 631366

x = 631366/100

x = 6313,66
