1/3+27/25÷9/5 2 2/3×[1 1/2+4/5 1/2×1 1/3+2/9:10/6

1/3+27/25÷9/5
= 1/3 + ( 27/25 x 5/9 )
= 1/3 + 3/5
= 5/15 + 9/15
= 14/15


2 2/3×[1 1/2+4/5 ]
= 8/3 x [ 3/2 + 4/5 ]
= 8/3 x [ 15/10 + 8/10 ]
= 8/3 x 23/10
= 92/15
= 6 2/15



1/2×1 1/3+2/9:10/6
= 1/2 x 4/3 + 2/9 : 10/6
= 4/6 + ( 2/9 x 6/10 )
= 2/3 + 2/15
= 10/15 + 2/15
= 12/15
= 4/5
