Question

Um sanduiche é feito com 270 gramas de carne. Quantos kg de carne são necessário para 200 desses sanduiches?​

Answer 1

Resposta:

1kg - 1000g

X - 270g

1000x= 270

270/1000= 0,27kg

0,27×200= 54kg

Answer 2

• A ↔

$\sf x\cdot \:1=270\cdot \:200\\\\\\x=270\cdot \:200\\\\\\\to \boxed{\sf =54,000/1000 \ => 54kg}$

• B ↔

$\sf 0.27x=1\cdot \:17.55\\\\\\0.27x=17.55\\\\\\0.27x\cdot \:100=17.55\cdot \:100\\\\\\27x=1755\\\\\\\dfrac{27x}{27}=\dfrac{1755}{27}\\\\\\\to \boxed{\sf =65}$
