1: 3/8 12 1/2

9/20 36 2/3

2/5 1/6 1/100

2: 5/12+2/3×3/4 3÷（5/7－3/14） (28+2/7×7/8)×1 /4

=5/12+1/2 =3÷(10/14－3/14) =(28+1/4)×1/4

=5 /12+6/12 =3÷1/2 =28×1/4+1/4×1/4

=11/12 =6 =7 y 1/16

3: (3/5+1/3)×15 7/13×4/5+6/13÷5/4

=3/5×15+1/3×15 = 7/13×4/5+6/13×4/5

=9+5 =4/5×(7/13+6/13)

=14 = 4/5×1

=4/5

（7/24－3/16）÷1/8 9/5－（2/5÷1/2+3 /7)

= (7/24-3/16)×8 = 9/5-(2/5×2+3/7)

=7/24× 8-3/16×8 =9/5-(4/5+3/7)

=7/3-3/2 =9/5-4/5-3/7

=5/6 =4/7
