7/10 -3/8 - 1/8 4/15 +5/6 1/2 -(3/4 -3/8 ) 5/6 -(1/3 +3/10 ) 2/3 +5/6
7/10 -3/8 - 1/8 4/15 +5/6 1/2 -(3/4 -3/8 ) 5/6 -(1/3 +3/10 ) 2/3 +5/6
7/10 -3/8 - 1/8=7/10-(3/8+1/8)=7/10-4/8=7/10-1/2=7/10-5/10=2/10=1/5
4/15 +5/6=8/30+25/30=33/30=11/10
1/2 -(3/4 -3/8 ) =1/2-(6/8-3/8)=1/2-3/8=4/8-3/8=1/8
5/6 -(1/3 +3/10 )=5/6-1/3-3/10=5/6-2/6-3/10=3/6-3/10=1/2-3/10=5/10-3/10=2/10=1/5
2/3 +5/6=4/6+5/6=9/6=3/2
