Answer:

0.72% ( 0.72 percent ) = 9:1250 ( 9 is to 1250 )

Step-by-step explanation:

Step 1) Convert the 0.72 percent to a decimal number.

To convert 0.72 percent to a decimal number, you divide 0.72 by 100. In other words, the quotient you get when you divide 0.72% by 100 is the decimal number.

0.72 ÷ 100 = 0.0072

Step 2) Convert the decimal number to a fraction.

To convert the decimal number to a fraction, we make the decimal number the numerator, and 1 the denominator.

0.0072 =

$\frac{0.0072}{1}$

Step 3) Remove the decimal point in the numerator.

To remove the decimal point in the numerator, multiply both the numerator and denominator by 10000.

$\frac{0.0072 \times 1000}{1 \times 10000} = \: \frac{72}{10000}$

Step 4) Simplify the fraction.

The greatest common factor of 72 and 10000 is 8. Therefore, to simplify the fraction, divide the numerator and denominator by 8.

$\frac{72 \div 8}{10000 \div 8} = \frac{9}{1250}$

Step 5) Convert the fraction to a ratio.

To convert the fraction to a ratio, replace the fraction divider line with a colon.

$\frac{9}{1250} = \: 9 \: is \: to \: 1250$

or 9:1250

That was the final step. Below is the answer to 0.72% as a ratio.

0.72% = 9:1250
