Answer:

Length of pieces are 3.125 m and 1.875 m

Explanation:

A piece of rope 5m long is cut into two pieces so that one piece is three fifths as long as the other.

Length of pieces be a and b.

Total length = 5 m

That is

a + b = 5

One piece is three fifths as long as the other

$a=(3)/(5)b\\\\a=0.6b$

Substituting

0.6 b + b = 5

1.6 b = 5

b = 3.125 m

a = 0.6 x 3.125 = 1.875 m

Length of pieces are 3.125 m and 1.875 m
