Jacob cuts 4 meters of a ribbon into 3 pieces, the length of the first piece is 1.28 meters. The length of the second one is 1.65 meters. Work out the length of the 3rd piece.

1.07meters

Step-by-step explanation:

Given data

Lenght of ribbon= 4 meters

Number of pieces= 3 pieces

Length of first piece= 1.28meters

Length of second piece= 1.65meters

Let the length of the third piece be x  meters

Hence

1.28+1.65+x= 4

2.93+x=4

x= 4-2.93

x=1.07meters

Hence, the length of the third piece is 1.07meters
