Final answer:
The correct symbol that makes the statement '24 tenths 2.5' true is the less than symbol (<), because 24 tenths, which is 2.4, is less than 2.5.
Step-by-step explanation:
To answer this, we need to compare '24 tenths' with the number '2.5'. First, let's convert '24 tenths' into decimal form. '24 tenths' is the same as 24 divided by 10, which equals 2.4. Now we can compare 2.4 and 2.5. Since 2.4 is less than 2.5, the symbol that makes the statement true is the less than symbol (<). This comparison underscores the numerical relationship, affirming that 24-tenths is indeed less than 2.5. It demonstrates the significance of converting fractions to decimals for accurate comparisons, clarifying the mathematical relationship between the given values, and supporting the logical interpretation of the less than symbol in this context.
