Step by step
The question
Question: write 5% as a decimal.
5%
1 Write it over 100
Percent means out of 100.
So 5% is 5/100.
= 5100
Careful!
5% is 5 out of 100, not out of 10.
Many people write 0.5.
Careful: not 5% = 0.5 ✗
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
5 hundredths is 0.05.
= 0.05
The short way: the point moves 2 places to the left.
5% → 0.05
the point moves 2 places left
3 Check
Let's check: go back.
0.05 is 5 hundredths.
So it is 5%.
So the answer is right!
Check: 0.05 = 5100 = 5%
Let's look back.
First: write it over 100.
Then: write the decimal.
Last: check.
Answer
= 0.05
