Question

Um hambúrguer e feito com 270 g de carne.

A)Quantos quilogramas são necessários para fazer 200 desses sanduíches?

B)Quantos desses sanduíches poderiam ser feitos com 17,55 Kg de carne?

Answer 1

A)
1 Sanduíche = 270g
200 Sanduíches = 200 . 270g
Resposta: 54.000g ou 54kg

B)
17,55kg = 17.550g
$\frac{17550}{270}$
= 65

Answer 2

• A ↔

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

• B ↔

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