Find 10% of each number. what pattern do you notice?
A. 10% of 30 is
B. 10% of 47 is
C. 10% of 240 is
D. 10% of 10.8 is
E. Describe the pattern that you notice.
The correct answer and explanation is:
To find 10% of each number, you multiply the number by 0.10 (which is the same as dividing by 10).
A. 10% of 30 is: 30×0.10=330 \times 0.10 = 3
So, 10% of 30 is 3.
B. 10% of 47 is: 47×0.10=4.747 \times 0.10 = 4.7
So, 10% of 47 is 4.7.
C. 10% of 240 is: 240×0.10=24240 \times 0.10 = 24
So, 10% of 240 is 24.
D. 10% of 10.8 is: 10.8×0.10=1.0810.8 \times 0.10 = 1.08
So, 10% of 10.8 is 1.08.
Pattern:
The pattern here is that 10% of a number is simply one-tenth of the number itself. The result can be a whole number, decimal, or fractional value depending on the original number.
For example:
- For 30, 10% is a whole number (3).
- For 47, 10% results in a decimal (4.7).
- For 240, 10% is a clean whole number (24).
- For 10.8, 10% is also a decimal (1.08).
The key observation is that 10% represents one-tenth, so the answer will always be smaller than the original number. If the original number is a whole number, the result may be a decimal if the original number is not divisible by 10. This rule holds true for all numbers, whether they are whole numbers or decimals. The result is always a tenth of the number, as shown in the examples above.
