Question

Для коридоров санаторного корпуса требуется 49 м 45 см ковровой дорожки. Остаток какой длины получится, если купили 50 м ковровой дорожки?

Answer 1

Остаток - разность чисел
РЕШЕНИЕ
1 м = 100 см
50 см = 1/2 м
50 - 49 1/2 = 1/2 м = 50 см - остаток - ОТВЕТ
Или
50  - 49,5  = 0,5 м = 50 см
Или
5000 - 4950 = 50 см 

Answer 2

Calculating the leftover length of carpet

The question asks us to calculate the leftover length of carpet if 49 meters 45 centimeters of carpet is needed for the corridors of a sanatorium building, and 50 meters of carpet was purchased.

To solve this, let's break it down step-by-step: 49 meters 45 centimeters is needed for the corridors. Converting centimeters to meters, this is 49.45 meters. 50 meters of carpet was purchased. To calculate the leftover length, we subtract the amount needed (49.45 meters) from the total purchased (50 meters). 50 meters - 49.45 meters = 0.55 meters leftover.

Therefore, the leftover length of carpet after accounting for the 49.45 meters needed, given that 50 meters was purchased, is 0.55 meters.
