1/100000000 is 1.0e-06% as a percent

Percent is derived from Latin word "per centum" which means "by a hundred". Percent can be thought of a fraction where denominator is always 100, and we add % sign to the fraction. For example, fraction 1/100000000 means 1.0e-06 %.

** Steps:**

First divide 1 by 100000000: 1 ÷ 100000000 = 1.0e-08

Then multiply by 100: 1.0e-08 × 100 = 1.0e-06

Answer:
\frac{1}{100000000}
= **1.0e-06%**

(Remember to put the "%" sign so people know it is "per 100")

OR you can multiply the top by 100 first then divide by the bottom number:

Multiply 1 by 100 first, then divide by 100000000

Or Move the Decimal 2 Places

After dividing, instead of multiplying by 100 we can just move the decimal point 2 places to the right, then add the %

First divide 1 by 100000000:

1 ÷ 100000000 = 1.0e-08

Move the decimal point 2 places to the right

2 places

Remember to add the "%" sign: 1.0e-06%

Lets say in a maths test, you score 19 marks out of 20, it means you scored 95%.

Lets say in a school with 250 students, 100 are boys, it means that the percentage of boys in school is 40 %
