Question

a rope was 9.45 meters. the length of the first piece of rope was 1/5 of the original length. the second piece of rope was 0.12 meter longer than the third piece.how long was the second piece of rope

Answer 1

first .2*9.45 = 1.89
remaining length = 9.45 - 1.89 = 7.56
so
piece 2 + (piece 2 - .12) = 7.56

2 * piece 2 = 7.68

piece 2 = 3.84
