**Modeling decimals worksheets :**

Worksheets on modeling decimals are much useful to the students who would to practice solving real world problems on decimals.

1. Model 0.78 by shading a 10-by-10 grid.

2. Model 0.53 by shading a 10-by-10 grid.

3. Model 1.42 by shading a 10-by-10 grid.

4. Model 1.07 by shading a 10-by-10 grid.

**Problem 1 :**

Model 0.78 by shading a 10-by-10 grid.

**Solution : **

Since there are two digits after the decimal point in 0.78, we can write 0.78 as a fraction 78/100.

So, we have

0.78 = 78 / 100 = 78%

(or)

0.78 = 78 out of a hundred

In 10 by- 10 grid, there will be 100 equal parts.

Because 10 x 10 = 100.

Since 0.78 = 78 out of a hundred, we have to shade 78 out 100 parts in 10 by- 10 grid to model the decimal 0.78

That is,

**Problem 2 :**

Model 0.53 by shading a 10-by-10 grid.

**Solution : **

Since there are two digits after the decimal point in 0.53, we can write 0.53 as a fraction 53/100.

So, we have

0.53 = 53 / 100 = 53%

(or)

0.53 = 53 out of a hundred

In 10 by- 10 grid, there will be 100 equal parts.

Because 10 x 10 = 100.

Since 0.53 = 53 out of a hundred, we have to shade 53 out 100 parts in 10 by- 10 grid to model the decimal 0.53

That is,

**Problem 3 :**

Model 1.42 by shading a 10-by-10 grid.

**Solution : **

There are two digits after the decimal point in 1.42. So, we can write 1.42 as a fraction 142/100.

Here, the numerator 142 is greater than 100.

Since we are going to use 10 by 10- grid (100 equal parts), we can write the given decimal 1.42 as given below.

In 1.42 = 1 42/100 or 1 + 42/100, there are two parts.

They are 1 and 42/100.

So, we have to use two 10 by-10 grids to model the decimal 1.42

Since we write 1.42 = 100/100 + 42/100, we have to shade all the 100 parts in the first grid and 42 parts in the second grid.

**Problem 4 :**

Model 1.07 by shading a 10-by-10 grid.

**Solution : **

There are two digits after the decimal point in 1.07. So, we can write 1.07 as a fraction 107/100.

Here, the numerator 107 is greater than 100.

Since we are going to use 10 by 10- grid (100 equal parts), we can write the given decimal 1.07 as given below.

1.07 = 1 + 0.07

1.07 = 100/100 + 7/100 = 1 7/100

In 1.07 = 1 7/100 or 1 + 7/100, there are two parts.

They are 1 and 7/100.

So, we have to use two 10 by-10 grids to model the decimal 1.07

Since we write 1.07 = 100/100 + 7/100, we have to shade all the 100 parts in the first grid and 7 parts in the second grid.
