0.5 meters

Step-by-step explanation:

In order to find the remaining amount of meters needed, we first need to find out how much Rita has as of now. To do that, we need to convert our lengths into meters.

1 meter=100 centimeters. Divide 250 centimeters by 100 to find how many meters it is. 250/100=2.5 meters

Next, 1 meter=1,000 millimeters. Divide 1,250 millimeters by 1,000 to find how many meters it is. 1,250/1000=1.25 meters

Add these lengths together (including the 3.75 meters). 1.25+2.5+3.75=7.5

Subtract this number from 8 to find the needed meters.

8-7.5=0.5

Rita needs 0.5 more meters of blue ribbon for her project.
