Question

se 7/8 de um terreno valem 21000 qual o valor de 5/48?

Answer 1

21000/7= 3000
1/8= 3000
3000.8= 24000
24000/48= 500
500.5= 2500
 
 O valor de 5 do terreno é 2500.
                  48

Answer 2

• Vamos descobrir o preço do terreno primeiro =>

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