Tia cut a 4-meter 8-centimeter wire into 10 equal pieces. Marta cut a 540-centimeter wire into 9 equal pieces. How much longer is one of Marta’s wires than one of Tia’s? First, Tia’s wire is 4 meters and 8 centimeters long, so that means it’s 408 centimeters long, then you divide that by 10:
tia = 408/10 = 40.8 cm

Now, Marta’s wire is 540 centimeters long and we have to divide that into 9 pieces:
Marta = 540/9 = 60 cm

Finally subtract Marta’s and Tia’s pieces: 60 - 40.8 = 19.2
So Marta’s pieces are 19.2 centimeters longer than Tia’s
