Answer 1

(-24)÷(-3/8)÷(-2/7)÷(-4/35)
=24×8/3÷(2/7)÷(4/35)
＝64×7/2÷4/35
＝224×35/4
＝1960
（-2）÷（-3/5)*4/5÷(-3又1/5)
= -2*5/3*4/5÷(16/5)
= -8/3 *5/16
=-5/6
(-2又2/3)÷(-1又7/9)
=8/3* 9/16
=3/2
(-1.4+14/15)÷(-7/30)
=(-2/5-1/15)÷(-7/30)
=7/15 * 30/7
=2
-3的2次方÷（-2又1/4）*(3/2)的3次方
=-9*(-4/9)*27/8
=27/2
（+3又1/2)+(-7.89)+(-2又1/2)+(-0.64)+(+7.89)+0.64
=（+3又1/2)+(-2又1/2)+(-0.64)+0.64+(+7.89)+(-7.89)
=3又1/2-2又1/2-0.64+0.64+7.89-7.89
=1
