Question

QUAL A FRAÇÃO GERATRIZ PARA: 3,04888... ?

Answer 1

$\mathsf{x=3,04888...\cdot1000}\\\mathsf{1000x=3048,888\cdot10}\\\mathsf{10000x=30488,888...}$

$-\underline{\begin{cases}\mathsf{10000x=30488,888...}\\\mathsf{1000x=3048,888...}\end{cases}}$

$\mathsf{9000x=27440}\\\mathsf{x=\dfrac{27440\div40}{9000\div40}}\\\huge\boxed{\boxed{\boxed{\boxed{\mathsf{x=\dfrac{686}{225}}}}}}$
