Rational multiplication: (+ 1 / 2) times (- 2 / 3) times (- 4 / 9)

1 / 2 * - 2 / 3 * - 4 / 9 = 4 / 27

(- 1) x (- 5 / 4) x15 / 8x (- 3 / 21x0x (- 1) rational multiplication

(- 1) x (- 5 / 4) x15 / 8x (- 3 / 21x0x (- 1) = 0
As long as the common factor is 0, the result is 0

Rational multiplication: 1, 2.25 * (- 2) * 3 / 25 =, 2, (- 2.1) * 10 / 9 * (- 3 / 7) =, 3, (- 85) * 9-25) * (- 4)=
3. (- 7 / 8) * 15 * (- 1 and 1 / 7)=

1、2.25*（-2）*3/25
=-4.5*3/25
=-0.54
2、（-2.1）*10/9*（-3/7）
=7/3*3/7
=1
3、（-85）*（9-25）*（-4）
=340*（-16）
=-5440
4. (- 7 / 8) * 15 * (- 1 and 1 / 7)
=7/8*8/7*15
=1*15
=15

Rational multiplication: 1, (17-25 + 8) * (- 31) =, 2, (- 3 and 1 / 3) * (+ 1.75) * (- 3 / 10) * (- 4 / 7)=

1、（17-25+8）*（-31）
=0*（-31）
=0
2. (- 3 and 1 / 3) * (+ 1.75) * (- 3 / 10) * (- 4 / 7)
=-（10/3*3/10）*（7/4*4/7）
=-1*1
=-1
