Uma balconista vendeu 70 centímetros de tecido a um freguês. Essa balconista preencheu corretamente a nota fiscal, escrevendo:
Evgesh-ka [11]

Answer:

Step-by-step explanation:

A clerk sold 70 centimeters of fabric to a customer. This clerk correctly filled out the invoice, writing:

1 point

a) 0.07 m

b) 0.070 m

c) 0.070 cm

d) 0.70 m

The clerk sold 70cm of fabrics

So, she want to filled the invoice but it length of fabrics sold must be in metre.

From metric units

100cm = 1m

Then,

70 cm = x

100cm = 1m

Cross multiply

70 cm × 1m = x × 100cm

Divide both side by 100cm

Then,

x = 70 cm × 1 m / 100cm

cm cancel out

x = 70 × 1m / 100

x = 70m / 100

x = 0.7m.

So, the correct answer is D.

To Portuguese

O funcionário vendeu 70cm de tecidos

Então, ela deseja preencher a fatura, mas o comprimento dos tecidos vendidos deve estar em metros.

De unidades métricas

100cm = 1m

Então,

70 cm = x

100cm = 1m

Multiplicação cruzada

70 cm × 1 m = x × 100 cm

Divida os dois lados por 100cm

Então,

x = 70 cm × 1 m / 100 cm

cm cancelar

x = 70 × 1m / 100

x = 70m / 100

x = 0,7 m.

Então, a resposta correta é D.
