Answer 1

3分之1+6分之5-10分之3
=2/6+5/6-3/10
=7/6-3/10
=35/30-9/30
=24/30
=4/5

5分之1-10分之1+3分之2
=2/10-1/10+2/3
=1/10+2/3
=3/30+20/30
=23/30

9分之8-(4分之3+8分之1)
=8/9-(6/8+1/8)
=8/9-7/8
=64/72-63/72
=1/72

(5分之3+4分之3)-4分之1
=3/5+3/4-1/4
=3/5-1/2
=6/10-5/12
=1/10

16分之13-(5分之1+8分之1）
=13/16-2/16-2/5
=11/16-2/5
=55/80-32/80
=23/80
