    ②(10/3 +3/4 -21/8 )×1

    =10/3 - 15/8

    =(8×10-15×3)/8×3

    =35/24

    ③3.5÷5/8 ×5/15

    =3.5×8/5×1/3

    =5.6×1/3

    =28/15

    ④0.8×2.7+7.3÷15/4

    =2.16+146/75

    =54/25+146/75

    =308/75

    ⑤9.8÷[28×(1-1/7 )+27/5 ]

    =9.8÷【28×6/7+5.4】

    =9.8÷(24+5.4)

    =9.8÷29.4

    =1/3
