Question

-0,81:(-27)=? - 1,1:2,2=? 1,6:(-3,2)=? 6:(-0,012) -6:0,015 1:0,25

Answer 1

Ответ:

Объяснение:

-81/100 : (-27/1) = -81/100 * -1/27=3/100=0,03

-1,1:2,2=-11/10 : 22/10=-11/10 * 10/22=-1/2=-0,5

1,6:(-3,2)=16/10 : -32/10 = 16/10 * -10/32 = -1/2 =-0,5

6:(-0,012) = 6000/1000: (-12/1000)=6000/1000 * -1000/12=-500

-6:0,015 = -6000/1000 : 15/1000 =-6000/1000 * 1000/15=-400

1:0,25 =100/100 : 25/100 = 100/100 * 100/25 = 4

Answer 2

Let's solve each of these mathematical expressions step by step:

1. -0.81: (-27): When dividing a negative number by another negative number, the result is positive. Therefore, -0.81 divided by -27 is equal to 0.03.

2. -1.1: 2.2: When dividing a negative number by a positive number, the result is negative. Thus, -1.1 divided by 2.2 is equal to -0.5.

3. 1.6: (-3.2): When dividing a positive number by a negative number, the result is negative. Hence, 1.6 divided by -3.2 is equal to -0.5.

4. 6: (-0.012): Dividing a positive number by a negative number yields a negative result. So, 6 divided by -0.012 is equal to -500.

5. -6: 0.015: Dividing a negative number by a positive number gives a negative result. Thus, -6 divided by 0.015 is equal to -400.

6. 1: 0.25: Dividing a positive number by a positive number results in a positive value. Therefore, 1 divided by 0.25 is equal to 4.

To summarize: -0.81: (-27) = 0.03 -1.1: 2.2 = -0.5 1.6: (-3.2) = -0.5 6: (-0.012) = -500 -6: 0.015 = -400 1: 0.25 = 4
