Step by step
The question
Question: write 150% as a decimal.
150%
1 Write it over 100
Percent means out of 100.
So 150% is 150/100.
= 150100
Careful!
150% is more than 100%.
So the decimal is more than 1.
Careful: more than 100% → more than 1
2 Write the decimal
100 has 2 zeros.
So the decimal has 2 digits after the point.
100: 2 zeros → 2 digits after the point
150 hundredths is 1.5.
= 1.5
The short way: the point moves 2 places to the left.
150% → 1.5
the point moves 2 places left
3 Check
Let's check: go back.
1.5 is 15 tenths.
That is 150/100.
So it is 150%.
So the answer is right!
Check: 1.5 = 1510 = 150100 = 150%
Let's look back.
First: write it over 100.
Then: write the decimal.
Last: check.
Answer
= 1.5
