Bria ordered 145 centimeters of fabric. Jayleen ordered 1.5 meters of fabric. Who ordered more fabric?
lubasha [3.4K]
Bria: 145 centimeters
Jayleen: 1.5 meters

I'm going to convert Jayleen's into centimeters:
1 meter has 100 centimeters

1.5 x 100 = 150 centimeters

so,
Bria:145 centimeters
Jayleen: 150 centimeters

So, Jayleen bought more fabric
