Answer:
8/35 de litro
Step-by-step explanation:
De la pregunta, sabemos que se necesitan 4/7 de un litro para pintar un metro cuadrado de pared.
Ahora necesitamos saber la cantidad de pintura necesaria para pintar 2/5 de un metro cuadrado.
Digamos que la cantidad necesaria es x
Ahora hagamos una relación matemática;
4/7 pinturas 1 metro cuadrado
x pintará 2/5 metros
cuadrados por lo tanto, x * 1 = 4/7 * 2/5 = 8/35
It will take 8/35 of a liter to paint 2/5 square meters of the house.
If it takes 4/7 of a liter of paint to paint a square meter of the wall, this can be expressed as;
4/7 of a liter = 1 square meter
To get the amount of paint need to paint 2/5 of a square meter of wall, we can write;
x = 2/5 square meters
Divide both expressions:
[tex]\frac{\frac{4}{7} }{x}= \frac{1 }{\frac{2}{5} }[/tex]
Cross multiply;
x = 4/7 * 2/5
x = 8/35
It shows that it will take 8/35 of a liter to paint 2/5 square meters of the house.
