Answer 1

Ответ:

Пошаговое объяснение:

1)1:0,5=10:5=2

2)1,6:0,16=160:16=10 3)0,75:2,5=7,5:25=0,3​​

Answer 2

1. 1:0.5 = x:5 = 2

To solve this proportion, we can cross-multiply.

1 * 5 = 0.5 * x

5 = 0.5x

To isolate x, divide both sides of the equation by 0.5:

5/0.5 = x

x = 10

So the missing value is 10.

2. 1.6:0.16 = 160:y = 10

Similarly, we can cross-multiply:

1.6 * y = 0.16 * 160

1.6y = 25.6

Divide both sides of the equation by 1.6:

y = 25.6 / 1.6

y = 16

Therefore, the missing value is 16.

3. 0.75:2.5 = x:25 = 0.3

Cross-multiplying:

0.75 * 25 = 2.5 * x

18.75 = 2.5x

Dividing both sides by 2.5:

18.75 / 2.5 = x

x = 7.5

So the missing value is 7.5.
