Final answer:
The symbol that results in a true number sentence when placed between the numbers sqrt(12.96), 3, and 3/5 is the less than symbol (<).
Step-by-step explanation:
The symbol that results in a true number sentence when placed between the numbers sqrt(12.96), 3, and 3/5 is the less than symbol (<).
To determine if the number sentence is true, we compare the value of sqrt(12.96) to the product of 3 and 3/5. If sqrt(12.96) is less than the product, then the number sentence is true.
In this case, sqrt(12.96) is approximately 3.6, and the product of 3 and 3/5 is 1.8. Since 3.6 is greater than 1.8, the number sentence is false.
