Which of the models represents the number 1.30?

a. | Model 1 | ||

b. | Model 2 | ||

c. | Model 3 | ||

d. | Model 4 |

The digit in the tenths position is represented by 10 hundredths, that is 10 colored pieces.

In the number, the digit in the tenths place is 3 and so, its value is represented by 3 tenths, which is 3 × 10 = 30 hundredths.

Represent 0.92 in the form of a grid model.

a. | Model 1 | ||

b. | Model 2 | ||

c. | Model 3 | ||

d. | Model 4 |

In the number, the integer part is zero. So, there should not be a completely shaded grid. In all the four choices, there is no completely shaded grid.

The digit in the tenths position is 9. So, it is represented by 9 tenths, that is 9 × 10 = 90 shaded pieces.

The digit in the hundredths place, which is 2 is represented by 2 hundredths, that is 2 shaded pieces.

So, 0.92 is represented by 90 + 2 = 92 hundredths. Thus, Model 1 is the correct answer.

Correct answer : (1)

4.
