Answer: 28%

Explanation: Since we need 2,600 mg of sodium for our daily amount, we just need to find how much percentage is 728 of 2,600. In other words, what fraction of a amount is 728 of 2,600. The easiest way to find out is to convert this into a fraction, then into a percentage by division.

Step 1.) Change to fraction.

728 of 2,600 is 728/2600

Step 2.) Change from fraction to decimal to a percentage.

Most of us already know that 1/2 is 50%, 3/4 is 75%, 1/5 is 20%, and so on... But the question is... How do you solve that with math?

To change a fraction to a percentage you divide the numerator (top) by the denominator (bottom).

Example: 1/2 = 1 divided by 2

If you know how to divide using decimals, then 1 divided by 2 will equal to .5 = 50% (You can use a calculator to check)

Note: To change a decimal to a percentage move the decimal two places to the right.

.5 = 50%

.75 = 75%

1.25 = 125%

Result .) Once we divide 2,600 by 728 we get 0.28 which is 28% after we convert it from decimal to percentage.

728/2600 = .28 = 28%

Your Welcome, hope this helps. :-)
