Question

a piece of wire 3/4 metre long was cut into 3 pieces. the first piece was 3/20 metre long, while the length of the second piece was 5/3 of the first. how long was the third piece?​

Answer 1

Step-by-step explanation:

Given:

Length of the Wire = 3/4 m

1st Piece = 3/20 m

2nd Piece = (5/3 - 3/20) m

3rd Piece = ?

Solution:

LCM of 4,20 and 3 = 60

Length of Wire = 3/4 * 15/15

=45/60 m

1st Piece = 3/20 * 3/3

=9/60 m

2nd Piece = 9/60 - 3/20

=9/60 - 9/60

= 0 m

3rd Piece = (3/4 - 0)

= 3/4 m
