Step by step
The question
Question: write 1/12 as a percent.
112
1 Multiply by 100%
Percent means out of 100.
But 12 does not go into 100 or 1000.
100% is all of it: 1 whole.
Times 1 does not change the size.
100% = 1 whole
So we multiply by 100%.
= 112 × 100%
1 times 100 is 100.
= 1 × 10012% = 10012%
100 and 12 can both be divided by 4.
That keeps the numbers small: 25/3 percent.
= 100 ÷ 412 ÷ 4% = 253%
2 Divide
25 divided by 3 is 8, with 1 left over.
25 ÷ 3 = 8 r 1
The 1 left over is still divided by 3: 1/3.
So it is 8⅓%.
= 813%
Careful!
8% is not exact.
The 1 left over is part of the answer too: a third more.
Careful: not 8% ✗
3 Check
Let's check.
12 times our answer should be 1 times 100%, because 12 times 1/12 is 1.
12 times 8 is 96.
12 times 1/3 is 4.
12 × 8% = 96%, 12 × 13% = 4%
96 plus 4 is 100%: one whole.
So the answer is right!
96% + 4% = 100% = 1 × 100%
Let's look back.
First: multiply by 100%.
Then: divide.
Last: check.
Answer
Careful: not 8% ✗
