Un frasco de perfume tiene la capacidad de 1/20 de litro. ¿cuántos frascos de perfume se pueden llenar con el contenido de una botella de 3/4 de litro?

15 frascos de perfume porque 3 / 4 = 15 / 20

Best answer that i found on yahoo ok   set :   x= length of 2nd piece in cm  x- 3= length of 1st piece in cm  x-4= length of 3rd piece in cm  then since you know they all came from the 20 cm ribbon you add them together and set them equal to 20x+ x-3 +x-4 = 20  3x - 7= 20  3x= 27  x= 9  the shortest piece is the third piece which is x- 4  x-4  9-4 = 5  the length of the smallest piece is 5 cm.  the other lengths are  9 cm  6 cm

You must find the surface of the block therefore 98187 dived by 5628 = 583m squared
