Question

A student says that 3% is equal to 0.3 when written as a decimal. Is their thinking correct? Explain.

Answer 1

no

Explanation:

0.3 = 30% not 3%

to change a percentage to a decimal fraction, divide by 100

3% =
`(3)/(100)` = 0.03

Answer 2

The answer is no.

Always remember when converting from percent to decimal, divide by 100%.

• 3% ÷ 100%
• 0.03 ≠ 0.3

Hence, the student's thinking is not correct.
