The problem asks us to compare given numbers with $1/2$ and put a tick in the appropriate column, whether they are "greater than $1/2$" or "less than $1/2$". The numbers to compare are 0.06, $\frac{11}{20}$, and 0.21. We are given that 0.9 is greater than $1/2$.

1. Problem Description

The problem asks us to compare given numbers with $1/2$ and put a tick in the appropriate column, whether they are "greater than $1/2$" or "less than $1/2$". The numbers to compare are 0.06, $\frac{11}{20}$, and 0.

1. We are given that 0.9 is greater than $1/2$.

2. Solution Steps

We need to compare each number with $1/2 = 0.5$.

* For 0.06:

Since $0.06 < 0.5$, we put a tick in the "less than $1/2$" column.

* For $\frac{11}{20}$:

We can convert the fraction to a decimal:

$\frac{11}{20} = \frac{11 \times 5}{20 \times 5} = \frac{55}{100} = 0.55$.

Since $0.55 > 0.5$, we put a tick in the "greater than $1/2$" column.

* For 0.21:

Since $0.21 < 0.5$, we put a tick in the "less than $1/2$" column.

3. Final Answer

Here's the completed table as described.

| Number | Greater than $\frac{1}{2}$ | Less than $\frac{1}{2}$ |

|---|---|---|

| 0.9 | $\checkmark$ | |

| 0.06 | | $\checkmark$ |

| $\frac{11}{20}$ | $\checkmark$ | |

| 0.21 | | $\checkmark$ |
