Question

b. how do you move the decimal point to find 1% of a number?

Explanation:

Step1: Recall the meaning of percentage

1% is equivalent to $\frac{1}{100}$ or 0.01 in decimal form.

Step2: Analyze the decimal movement

To find 1% of a number, we multiply the number by 0.01. Multiplying by 0.01 is the same as dividing by 100. When we divide a number by 100, we move the decimal point two places to the left. For example, if the number is 500, 1% of 500 is $500\times0.01 = 5$, and moving the decimal point in 500 (which can be written as 500.0) two places to the left gives 5.0, which is 5. If the number is 3.25, 1% of 3.25 is $3.25\times0.01=0.0325$, and moving the decimal point in 3.25 two places to the left gives 0.0325.

Answer:

To find 1% of a number, you move the decimal point two places to the left.
