five-ninths, 5 _ 9
Firstly, do 11 minus 4 = 7. So, now we have 7 and two ninths, minus five ninths. Much easier, 6 and 6 ninths.
It is: 8/9 minus 5/6 = 1/18
seven ninths
3/9 (three ninths), which can be reduced to 1/3 (one third).
Eight minus one and one ninth equals six and eight ninths.
Two thirds minus two ninths is 4 ninths. Two thirds is 6 ninths. 6 ninths minus 2 ninths is 4 ninths.
6/9 minus 6/9 = Zero.
five-ninths, 5 _ 9
3 6/9 or 3 2/3 or 11/3
Firstly, do 11 minus 4 = 7. So, now we have 7 and two ninths, minus five ninths. Much easier, 6 and 6 ninths.
8/9 - 6/9 = 2/9
It is: 8/9 minus 5/6 = 1/18
seven ninths
3/9 (three ninths), which can be reduced to 1/3 (one third).
8/9 minus 7/8 = 1/72
1/3=3/9 (8/9)-(3/9)=5/9
