A piece of rope is 70 inches long is to be cut into 2 pieces How long will each piece be if one piece is cut four times longer t

liq [111]

The long piece is 4 times the length of the short piece.

Short piece = 1 time
Long piece = 4 times
--------------------------------
Full rope = 5 times

5 times = 70 inches

Divide each side by 5 : 1 time = 14 inches

Short piece = 1 time = 14 inches

Long piece = 4 times = 4 x 14inches = 56 inches

Check:

Ratio of long to short = 56inches / 14inches = 4

Sum of both pieces = (56 + 14) = 70 inches

yay !
