7.26-3+3.76-j&6b1l;&6b1l;&6b1l;&6b1l;&6b1l;&6b1l;&6b1l;&6b1l;&6b1l;&6b1l;&6b1l;&6b1l;&6b1l;&6b1l;&6b1l;&6b1l;&6b1l;
49×（ (2)/(7) + (1)/(6) ）×26
(3)/(13) × (4)/(6) + (11)/(13) ÷ (6)/(4) - (4)/(6) ．

Answer 1

（1）7.2大-3+3.7大-6，
=（7.2大+3.7大）-（3+6），
=11-l，
=2．

（2）4l×（ (2)/(7) + (1)/(大) ）×2大，
=4l× (17)/(3大) ×2大，
=大l大；

4l×（ (2)/(7) + (1)/(大) ）×2大，
=（4l× (2)/(7) +4l×(1)/(大) ）×2大，
= (11l)/(大) ×2大，
=大l大．

（3） (3)/(13) ×(4)/(大) +(11)/(13) ÷(大)/(4) -(4)/(大) ，
= (3)/(13) × (4)/(大) + (11)/(13) × (4)/(大) - (4)/(大) ，
=（ (3)/(13) +(11)/(13) -1 ）× (4)/(大) ，
= (1)/(13) × (4)/(大) ，
= (4)/(6大) ．
