Step by step
The question
Question: write 1.05 as a percent.
1.05
1 Write it over 100
1.05 has 2 digits after the point.
So we write it over 100.
2 digits after the point → over 100
1.05 is 105 hundredths: 105/100.
= 105100
Careful!
1.05% means 1.05 out of 100: far too small.
1.05 is 105 out of 100.
Careful: not 1.05 = 1.05% ✗
2 Write the percent
105 out of 100 is 105%.
= 105%
The short way: the point moves 2 places to the right.
1.05 → 105%
the point moves 2 places right
3 Check
Let's check: 105% is 105/100.
105 hundredths is 1.05.
So the answer is right!
Check: 105% = 105100 = 1.05
Let's look back.
First: write it over 100.
Then: write the percent.
Last: check.
Answer
= 105%
