0.1/10 is 1.0% 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 0.1/10 means 1.0 %.

** Steps:**

First divide 0.1 by 10: 0.1 ÷ 10 = 0.01

Then multiply by 100: 0.01 × 100 = 1.0

Answer:
\frac{0.1}{10}
= **1.0%**

(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 0.1 by 100 first, then divide by 10

10.0 ÷ 10 = 1.0

Answer:
\frac{0.1}{10}
= **1.0%**

(Remember that "%" sign!)

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 0.1 by 10:

0.1 ÷ 10 = 0.01

Move the decimal point 2 places to the right

2 places

Remember to add the "%" sign: 1.0%

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 %
