Question

1.-3 1/2*(-4/7) 2.-65*(-1) 3.1 1/8 *(-5 1/3) 4.-1 1/3*1,8 5. 7,4*(-1) 6.-62,5*0​

Answer 1

Ответ:

Пошаговое объяснение:

1.-3 1/2*(-4/7) =-7/2*(-4/7)=2

2.-65*(-1) =65

3.1 1/8 *(-5 1/3) =9/8*(-16/3)=-6

4.-1 1/3*1,8=-4/3*9/5=-12/5=-2,4

5. 7,4*(-1) =-7,4

6.-62,5*0​=0

Answer 2

Sure, I'd be happy to help you with these calculations:

1. $-3 \frac{1}{2} \times \left(-\frac{4}{7}\right) = \frac{29}{14} \approx 2.0714$
2. $-65 \times (-1) = 65$
3. $1 \frac{1}{8} \times (-5 \frac{1}{3}) = -6 \frac{19}{24} \approx -6.7917$
4. $-1 \frac{1}{3} \times 1.8 = -2.4$
5. $7.4 \times (-1) = -7.4$
6. $-62.5 \times 0 = 0$

Please note that the results are rounded to a reasonable number of decimal places. If you need more accurate calculations, you can perform them using a calculator or a computational tool.
