10% of a number is equal to the number multiplied by ten. i can move the decimal point one place to the right to find the answer.
10% of a number is equal to the number subtracted by ten. i can subtract 1 from the tens digit to find the answer.
10% of a number is equal to the number divided by ten. i can move the decimal point one place to the left to find the answer.
10% of a number is equal to the number added to ten. i can add 1 to the tens digit to find the answer.

Explanation:

To determine the correct statement about 10% of a number, recall the definition of percentage. 10% is equivalent to \( \frac{10}{100} = \frac{1}{10} \). So, 10% of a number \( n \) is \( n \times \frac{1}{10}=\frac{n}{10} \). Dividing a number by 10 is the same as moving the decimal point one place to the left (e.g., 50 → 5.0 when taking 10%: \( 50\times0.1 = 5 \), decimal moved left once). The other options are incorrect: multiplying by 10 (right decimal) is for 1000% etc., subtracting/adding ten is not related to 10% of a number.

Answer:

10% of a number is equal to the number divided by ten. I can move the decimal point one place to the left to find the answer.
