how I change 28/9 to a mixed or whole number

divide 28 by 9 to give you 3 with a remainder of 1.

so 28/9 = 3 1/9 (three and one ninth)

Thank you Reiny

To change a fraction into a mixed number or whole number, you need to divide the numerator (top number) by the denominator (bottom number).

In this case, you have the fraction 28/9. Divide 28 by 9:

28 ÷ 9 = 3 with a remainder of 1.

The quotient is 3, and the remainder is 1.

So, 28/9 can be expressed as a mixed number: 3 1/9 (read as "three and one ninth"). The whole number part is 3, and the fraction part is 1/9.
