To find the number that is 25% smaller than 24, we will follow these steps:
1. Determine the percentage to decrease:
25% of 24 needs to be calculated.
2. Calculate the amount to decrease:
To find 25% of 24, we multiply 24 by 0.25 (since 25% is the same as 0.25 in decimal form).
[tex]\[
24 \times 0.25 = 6
\][/tex]
This means 25% of 24 is 6.
3. Subtract the decrease from the original number:
Subtract the calculated decrease (6) from the original number (24):
[tex]\[
24 - 6 = 18
\][/tex]
Thus, the number that is 25% smaller than 24 is 18.
As an additional note, the decrease amount is 6, and the new number after the decrease is 18.
