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.
