Question

Tia cut 4 meter 8 centimeter wire into 10 equal pieces. Marta cut 540 centimeter wire into 9 equal pieces . How much longer is one of Marta's wire than one of Tia's

Answer 1

19.2 centimeters

Explanation:

Tia cut a 4 meter and 8 centimeter wire, converting this measure to centimeters

`4m + 8 cm = 400cm + 8cm =408 cm`

and she cut it into 10 equal pieces, thus each piece measures:

`(408cm)/(10)=40.8cm`.

Martha has a wire of 540 centimeter wich she cutted into 9 equal pieces, so each piece measures:

`(540cm)/(9) =60cm`

The difference between the two wires is:

`60cm - 40.8cm=19.2cm`
