Final answer:
The length of the remaining piece of ribbon, after cutting three 85 cm pieces from 3 meters, is 45 cm.
Explanation:
The subject of the question is a simple mathematical calculation involving length measurements. To answer the student's question of how much ribbon is left after cutting 3 pieces of 85 cm each from a 3 meter long ribbon, firstly we need to convert all measurements to the same units. In this case, we'll convert meters to centimeters since the pieces cut are given in centimeters. As there are 100 cm in a meter, 3 meters equates to 300 cm. Next, calculate the total length of the cut pieces by multiplying the length of one piece (85 cm) by the number of pieces (3), which equals 255 cm. Subtract this total from the original length (300 cm) to find the length of the remaining ribbon. Hence, 300 cm - 255 cm = 45 cm. So, the length of the remaining piece of ribbon is 45 cm.
