Answer 1

Olá....

a)

100% de R$700

100% -----700

100%------x

100x = 100.700

100x = 70 000

x = 70 000/100

x = 700

10% de 700

100%----700

10%------x

100x = 10.700

100x = 7 000

x = 7 000/100

x = 70

1% de 700

100%-----700

1%---------x

100x = 1.700

100x = 700

x = 700/100

x = 7

b)

50% de R$1 000

100%------1 000

50%--------x

100x = 50.1 000

100x = 50 000

x = 50 000/100

x = 500

10% de R$1 000

100%--------1 000

10%----------x

100x = 10.1 000

100x = 10 000

x = 10 000/100

x = 100

5% de R$1 000

100%-----1 000

5%--------x

100x = 5.1 000

100x = 5 000

x = 5 000/100

x = 50

c)

1% de R$900

100%-------900

1%----------x

100x = 1.900

100x = 900

x = 900/100

x = 9

2% de R$900

100%--------900

2%-----------x

100x = 2.900

100x = 1 800

x = 1 800/100

x = 18

4% de R$900

100%--------900

4%-----------x

100x = 4.900

100x = 3 600

x = 3 600/100

x = 36

Espero ter ajudado.
