Final answer:
When -1.25 is multiplied by √17, the result is an irrational number.
Step-by-step explanation:
When a number is multiplied by -1.25, the result is the negative value of the original number. The question asks for a number that produces an irrational number when multiplied by -1.25. An irrational number is a number that cannot be expressed as a fraction or a decimal that terminates or repeats.
To determine if a number is irrational, we can check if its square root is irrational. Therefore, we need to find a number whose square root is irrational when multiplied by -1.25. The number √17 satisfies this condition. When -1.25 is multiplied by √17, the result is an irrational number.
