If it can be expressed as a ratio of whole numbers ... like "two out of nine" ... then it is by definition a rational number.
yes
Five-ninths must be added to four-ninths to make a whole.

One whole is nine ninths. Nine ninths minus four ninths equals five ninths.
5/9 is a fraction and it cannot be converted into a whole number.
2 4/9 (two and four ninths)
yes
To convert a mixed number to an improper fraction, multiply the denominator by the whole number, add that total to the numerator and put the whole thing over the original denominator. 20/9
Five-ninths must be added to four-ninths to make a whole.
The answer is -3.5
two fifths
Two thirds minus two ninths is 4 ninths. Two thirds is 6 ninths. 6 ninths minus 2 ninths is 4 ninths.
Ninths means you have something divided into 9 pieces. So how many equal one whole? All 9 pieces! But you don't have one whole, you really have eight. So if 9 pieces are in one whole, ____ x 1 = 8? Multiply this number by the 9 pieces in each whole one and you'll have your answer!
