0.625*5.8+5/8*3.2-5/8
=(5/8)*5.8+(5/8)*3.2-(5/8)
=(5/8)(5.8+3.2-1)
=(5/8)(9-1)
=(5/8)*8
=5
1.36-2/7+5/8*3.2-5/8
=1.36-2/7+5/8(3.2-1)
=1.36-2/7+5/8*(2.2)
=34/25-2/7+11/8
=(238-50)/175+11/8
=188/175+11/8
=(1504+1925)/1400
=3429/1400
=2又629/1400
(1/24+2/23)*23+1/24
=23/24+2+1/24
=(23/24+1/24)+2
=1+2
=3
