The length of the rectangle is 5 1/6 m and the width is 1 5/6 m less. What is the width of the rectangle?

The length is (5 and 1/6) meters. Let’s translate into an incorrect fraction – 31/6 meters. The width is less than the lengths by (1 and 5/6) meters, again we translate into an incorrect fraction – 11/6 – and consider:
31/6 – 11/6 = 20/6 (m) – the width of the rectangle.
20/6 = 3 integers and 2/6 = 3 integers and 1/3 meters.
Answer: the width of the rectangle is equal to 3 integers and 1/3 of a meter.
