Question

Choose the correct expression from the following options.

• A. $10.1>10.3$
• B. $10.3>10.5$
• C. $10.3<10.5$
• D. $10.5<10.1$

Answer 1

The correct option is C $10.3<10.5$

All the numbers have the same whole part, $10$. So, their decimal parts can be compared to decide the appropriate symbol.

A. Compare $10.1$ and $10.3$, the whole part is the same and the decimal part, $0.1$ is less than $0.3$. So $10.1<10.3$

B. Compare $10.3$ and $10.5$, the whole part is the same and the decimal part, $0.3$ is less than $0.5$. So $10.3<10.5$

C. Compare $10.3$ and $10.5$, the whole part is the same and the decimal part, $0.3$ is less than $0.5$. So $10.3<10.5$

D. Compare $10.5$ and $10.1$, the whole part is the same and the decimal part, $0.1$ is less than $0.5$. So $10.1<10.5$

From the given options, the expression $10.3<10.5$ is correct.
