1/4x15/8x16/5x4
=(1/4x4)x(15/8x16/5)
=1x6
=6
(1÷2/9-3/4x2)÷1/2
=(9/2-3/2)x2
=3x2
=6
35-7/9÷5/9x3/14
=35-7/9x9/5x3/14
=35-3/10
=34又7/10
2/3x1/3÷(4/5-8/15)
=2/9÷4/15
=2/9x15/4
=5/6
7/15x0.8+8/15x4/5
=7/15x0.8+8/15x0.8
=(7/15+8/15)x0.8
=1x0.8
=0.8
5/4-7/15-8/15
=5/4-(7/15+8/15)
=5/4-1
=1/4
=(1/4x4)x(15/8x16/5)
