=5/8÷(1/4 + 7/8)
=5/8÷9/8
=5/8 * 8/9
=5/9

5/8×7+9÷
8/5,
=5/8x7+9x5/8
=(7+9)x5/8
=16x5/8
=1015÷(2/3-1/5)
=15÷(10/15-3/15)
=15÷7/15
=225/7
6/5×2/15+2/15÷5/4
=2/15x6/5+2/15x4/5
=2/15x(6/5+4/5)
=2/15x2
=4/15
脫式計算:5/8÷75%- 2/19×38% (3/8+37.5%)÷(2.1-209%) 2.5×125×32

5/8÷75%- 2/19×38%
=5/8×100/75-2/19×38/100=5/6-1/25
=119/150
(3/8+37.5%)÷(2.1-209%)=(0.375+0.375)÷(2.1-2.09)=0.75÷0.1
=0.75×10
