A 42-inch board is to be cut into three pieces so that the second piece is twice as long as the first piece and the third piece is 3 times as long as the first piece . If x

If the length of the first piece is x then the others are of lengths 2x and 3x.

Furthermore,

[tex]42=x+2x+3x=6x[/tex]

Divide both ends by [tex]6[/tex] to find

[tex]x=7[/tex]

So the first piece is of length 7 inches and the other two are 14 inches and 21 inches.
