Respuesta: 3 19/21 metros

Explicación paso a paso:

Dado que :

Metros de tela azul comprados = 1 4/7 metros

Metros de tela verde comprada = 2 1/3 metros

Metros de tela comprados en total:

Suma de metros de tela azul y verde;

(metros de tela azul + metros de tela verde)

(1 4/7) + (2 1/3)

11/7 + 7/3

L.C.M de 7 y 3 = 21

(33 + 49) / 21

= 82/21

= 3 19/21 metros
