Can someone explain how u can write a percent in simplest form?

The answer is 1 1/4 or a.

Step-by-step explanation:

Basicallly percents are based of 100% so there is a 100% which would be a whole then there is only 25% and if you take 4 quarters and each quarter is 25 cents and there is 4 quarters in a whole that would be 1/4. You add the 1 whole and the 1/4 to get 1 1/4.

Hope this helps, tried to explain it in the best way I can.

answer set (b) 0.5, 3/4 80% is in order from least to greatest.  

step-by-step explanation:

in order to compare rational numbers to each other, it is much easier if they are in the same form.   typically, the best form in which to evaluate rational numbers is in decimals.   in order to convert a percent to a decimal, you would divide the given percentage by 100.   you can also accomplish the conversion by moving the decimal point over two places to the left.   for example, the decimal value of 80% is 80/100, or 0.8.   in order to convert a fraction to a decimal, you need to divide the numerator by the denominator.   for example, 3/4 is 0.75.   so, for choice (b) 0.5 3/4 (0.75), 80% (0.8) is the only choice in which the numbers are in order from least to greatest.
