One third is three ninths. So one ninth minus three ninths is minus two nights.
1 third = 3 ninths, 3 ninths - 2 ninths = 1 ninth.
Four and two thirds divided by one and three ninths = 7/2 or 31/2
two thirds minus one ninth equals five ninths in its simplest form
One whole is nine ninths. Nine ninths minus four ninths equals five ninths.
It is: 12 and 4/9 minus 1 and 2/3 = 10 and 7/9
3/9 (three ninths), which can be reduced to 1/3 (one third).
six and two thirds
Two thirds is four sixths. One sixth minus four sixths is minus three sixths, which is also minus one half.
