Final Answer:
Option 1: Statement 1 - This option is true.
Option 2: Statement 2 - This option is false.
Option 3: Both statements - This option is not correct because Statement 2 is false.
Option 4: Neither statement - This option is not correct because Statement 1 is true.
Step-by-step explanation:
Statement 1: "5/15 is rational"
To determine whether this statement is true, we need to understand what a rational number is. A rational number is any number that can be expressed as the ratio of two integers, where the denominator is not zero.
The fraction 5/15 is equivalent to 1/3 after simplification (because both the numerator and denominator can be divided by 5).
Since 1 and 3 are both integers and 3 is not zero, 5/15 (or 1/3) can indeed be expressed as the ratio of two integers.
Therefore, 5/15 is a rational number, and Statement 1 is true.
Statement 2: "3.8 is irrational"
To evaluate this statement, we again need to refer to the definitions. A number is irrational if it cannot be expressed as a ratio of two integers.
However, 3.8 can be expressed as the fraction 38/10, which simplifies further to 19/5 (by dividing both numerator and denominator by 2). 19 and 5 are both integers, and 5 is not zero, which means that 3.8 is the ratio of two integers.
As a result, 3.8 is a rational number, not an irrational one, so Statement 2 is false.
Therefore, the correct answer to the question is Option 1: Statement 1.
