The question

Question: write 1/9 as a percent.

19

1 Multiply by 100%

Percent means out of 100.

But 9 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%.

= 19 × 100%

1 times 100 is 100.

So it is 100/9 percent.

= 1 × 1009% = 1009%

2 Divide

100 divided by 9 is 11, with 1 left over.

100 ÷ 9 = 11 r 1

The 1 left over is still divided by 9: 1/9.

So it is 11 and 1/9%.

= 1119%

Careful!

11% is not exact.

The 1 left over is part of the answer too: 1/9 more.

Careful: not 11% ✗

3 Check

Let's check.

9 times our answer should be 1 times 100%, because 9 times 1/9 is 1.

9 times 11 is 99.

9 times 1/9 is 1.

9 × 11% = 99%, 9 × 19% = 1%

99 plus 1 is 100%: one whole.

So the answer is right!

99% + 1% = 100% = 1 × 100%

Let's look back.

First: multiply by 100%.

Then: divide.

Last: check.

Careful: not 11% ✗
