10x4/9-4/9
=4/9x(10-1)
=4/9x9
=4
(1/6+1/7)x6x7
=1/6x6x7+1/7x7x6
=7+6
=13
0.6+3/5x5/8-3/8x60%
=0.6+3/8-3/8x0.6
=0.6+3/8x(1-0.6)
=0.6x3/8x0.4
=0.6+1.2/8
=0.6+0.15
=0.75
3/4÷3+3/8
3/4x1/3+3/8
=1/4+3/8
=2/8+3/8
=5/8
5/8x5/12+5/12÷8/3
=5/12x(5/8+3/8)
=5/12x1
=5/12
2.9x(3.8-4/5)÷(13/8+5/8)
=2.9x2x8/18
=5.8x8/18
=58/10x8/18
=29/5x8/9
=232/45(45分之232)
