Question

Начертите в тетради координатный луч с единичным отрезком 10 сантиметров отметьте на нём Точки которые соответствуют числам 0.3 0.5 0.75 1.2 1.8 2.25

Answer 1

Длиной 10 см  в единичном отрезке и 2,25 - получится  22,5 см - много.
На рисунке - единичный отрезок - 5 см - 10 клеток.

Answer 2

Drawing a Coordinate Ray

To draw a coordinate ray with a unit length of 10 centimeters, we can start by drawing a horizontal line segment. We will mark points on this line segment that correspond to the given numbers: 0.3, 0.5, 0.75, 1.2, 1.8, and 2.25.

Here's how you can draw the coordinate ray in your notebook:

1. Start by drawing a horizontal line segment of length 10 centimeters. Label one end as the origin (0) and the other end as 10.

2. Divide the line segment into 10 equal parts. Each part will represent 1 centimeter.

3. Mark the points on the line segment that correspond to the given numbers: 0.3, 0.5, 0.75, 1.2, 1.8, and 2.25.

- To mark the point corresponding to 0.3, measure 3 centimeters from the origin (0) and make a small mark. - To mark the point corresponding to 0.5, measure 5 centimeters from the origin (0) and make a small mark. - To mark the point corresponding to 0.75, measure 7.5 centimeters from the origin (0) and make a small mark. - To mark the point corresponding to 1.2, measure 12 centimeters from the origin (0) and make a small mark. - To mark the point corresponding to 1.8, measure 18 centimeters from the origin (0) and make a small mark. - To mark the point corresponding to 2.25, measure 22.5 centimeters from the origin (0) and make a small mark.

4. Label each of the marked points with their respective numbers: 0.3, 0.5, 0.75, 1.2, 1.8, and 2.25.

Your coordinate ray should now be complete, with the marked points representing the given numbers.

Please note that the measurements mentioned above are approximate and can be adjusted based on the scale you are using in your notebook.
