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?

Marta's wire is 19.2 cm longer than Tia's wire.

Given:

Tia 's wire is 4m 8 cm ⇒ cut into 10 equal pieces

Marta's wire 540 cm ⇒ cut into 9 equal pieces

Question:

How much longer is one of Marta's wires then one of Tia's?

1. Tia's wire is in m and cm unit, so we can not divide it straightly into its equal pieces. First step, we are going to convert meter (m) to millimeter (mm):

Tia's wire = 4 m 8 cm

2. Second step, calculate each pieces Tia's wire:

She cut this wire into 10 equal pieces:

Each piece of Tia's s ribbon is is 40.8 cm long

3. Third step, we are going to calculate Marta's wire:

She has 540 cm and cut it into 9 equal pieces

Each pieces Marta's wire is 60 cm long

4. Last step, find the difference between Tia's wire and Marta's:

So, Marta's wire is 19.2 cm longer than Tia's wire
