I know how to multiply ,but i have to
use it in a model.
0.2 x 0.7 the answer is 1.4
show my how to use a model to solve.
The answer is not 1.4
You have two decimal places in the problem, so you need two decmal places in the answer.
Run this through your calculator.
0.2 x 0.7 = 0.14
3x0.5 is the answer 15.0 how can i used it aas a model.
0.5 = 1/2
Half of 3 is not 15.
To use a model to solve the multiplication problem 0.2 x 0.7, you can use a grid or an area model. Let's use the area model.
1. Draw a rectangle and divide it into 10 equal vertical sections to represent the first number, 0.2.
2. Shade in 2 out of the 10 sections to represent 0.2.
```
0.2
-----------
| ▓▓░░░░░░░|
| ▓▓░░░░░░░|
| ░░░░░░░░░|
| ░░░░░░░░░|
| ░░░░░░░░░|
-----------
```
3. Next, divide the rectangle into 10 equal horizontal sections to represent the second number, 0.7.
4. Shade in 7 out of the 10 sections to represent 0.7.
```
0.2
-----------
| ▓▓░░░░░░░|
| ▓▓░░░░░░░|
| ░░░░░░░░░|
| ░░░░░░░░░|
| ░░░░░░░░░|
-----------
0.7
```
5. Now, count the number of shaded sections in the model. In this case, there are 14 shaded sections.
6. Each shaded section represents 0.01 because 0.2 divided by 10 is 0.02 and 0.7 divided by 10 is 0.07.
7. Therefore, when you multiply 0.2 by 0.7, the result is 0.02 + 0.07 = 0.14.
So, the answer to 0.2 x 0.7 using a model is 0.14.
