Question

Se 7/8 de um terreno valem R$ 21.000,00, Qual é o valor de 5/48 do mesmo terreno?

Answer 1

7/8 ____21000
8/8____x

x= 21000.8/7
x= 168000/7
x=24000

O terreno inteiro vale 24000

Então

24000_____ 1
x _________5/48

x= 24000.5/48
x= 120000/48
x=2500

O valor de 5/48 do terreno vale R$ 2500,00

Answer 2

• Vamos descobrir o preço do terreno primeiro =>

$\tt 21,000\div \:7\cdot \:8\\\\\\\tt =300\cdot \:8\\\\\\\boxed{\boxed{\tt =24000 }}\\\\\\\tt 24000\div \:48\cdot \:5\\\\\\\tt =500\cdot \:5\\\\\\\to \large \boxed{\boxed{{\tt =2500}}}$
