Qual é a fração geratriz de 4,7444...

Answer 1

$\mathsf{x=4,74444...\times10}\\\mathsf{10x=47,444... \times10}\\\mathsf{100x=474,444...}$

$\underline{\begin{cases}\mathsf{100x=474,444... }\\\mathsf{10x=47,444...}\end{cases}}$

$\mathsf{90x=427}\\\large\boxed{\boxed{\boxed{\boxed{\mathsf{x=\dfrac{427}{90}}}}}}$
