Question

Choose the model which represents the smaller decimal number.

• A.
• B.

Answer 1

The correct option is B

In the 1st model, we have 2 wholes.

Each whole is divided into 10 equal parts.

The first whole represents 10 shaded parts out of 10 parts.
$\therefore$ It represents $\frac{10}{10}=1$

The second whole represents 6 shaded parts out of 10 parts.
$\therefore$ It represents $\frac{6}{10}=0.6$

Hence, the first model represents $1+0.6=1.6$

In the 2nd model, we have 1 whole.

It is also divided into 10 equal parts.

Here, 6 out of 10 parts are shaded.
$\therefore$ It represents $\frac{6}{10}=0.6$

As $0.6<1.6$, the 2nd model represents a smaller decimal number.
