Step by step
The question
Question: write 2% as a decimal.
2%
1 Write it over 100
Percent means out of 100.
So 2% is 2/100.
= 2100
Careful!
2% is 2 out of 100, not out of 10.
Many people write 0.2.
Careful: not 2% = 0.2 ✗
2 Write the decimal
100 has 2 zeros.
So the decimal has 2 digits after the point.
We fill the gap with a 0 after the point.
100: 2 zeros → 2 digits after the point
2 hundredths is 0.02.
= 0.02
The short way: the point moves 2 places to the left.
2% → 0.02
the point moves 2 places left
3 Check
Let's check: go back.
0.02 is 2 hundredths.
So it is 2%.
So the answer is right!
Check: 0.02 = 2100 = 2%
Let's look back.
First: write it over 100.
Then: write the decimal.
Last: check.
Answer
= 0.02
