C) twenty-eight and nine tenths
<u><em>Explanation:</em></u>
We have two parts here, the whole number and the decimal part.
<u>1- for the whole number,</u> it is read normally as counting numbers. Therefore, 28 is read as twenty-eight
<u>2- for the decimal part, </u>it is read based on the place-value of the number. We know that the first number after the decimal point is in the tenth position. This means that 0.9 is read as nine tenths
<u>Combining the two,</u> we would conclude that 28.9 is read as twenty-eight and nine tenths
