✔ 最佳答案
9/10*(5 5/12-1/4)=9/10*(5 5/12 - 3/12)
=9/10*5 2/12
=4 13/20
1 1/3 ÷1 7/9 ÷5/6
=4/3*9/16*6/5
=9/10
1 5/7 + 2 2/3 * 3 9/14
=1 5/7 + 45 1/3
=1 15/21 + 45 7/21
=47 1/21
1 1/4 -7/16 ÷3/4
=1 1/4 - 7/16 * 4/3
=1 1/4 -7/12
=1 3/12 - 7/12
=8/12
= 2/3
(2 5/6 - 1 2/3) ÷ 1 1/6
=(2 5/6 - 1 4/6) ÷ 1 1/6
= 1 1/6 ÷1 1/6
=1
2 1/2 ÷ ( 2 1/3 -5/6)*3/4
=2 1/2 ÷ ( 2 2/6 -5/6)*3/4
=2 1/2 ÷ 1 1/2*3/4
=1 1/4
