Answer 1

Ответ:

Не до конца понял, что тут у вас происходит, так что к первой пропорции прилагается дополнительный вариант.

Answer 2

To solve the equations, let's break them down step by step.

Equation 1: 1 * (2/x) = 8/5

To isolate the variable, we can cross-multiply: 1 * (2/x) = 8/5 5 * 2 = 8 * x 10 = 8x

Dividing both sides by 8: 10/8 = x 5/4 = x

So x = 5/4.

Equation 2: 4.8/5.1 = x34

To solve for x, we can cross-multiply: 4.8/5.1 = x/34 4.8 * 34 = 5.1 * x 163.2 = 5.1x

Dividing both sides by 5.1: 163.2/5.1 = x 32 = x

So x = 32.

Equation 3: x/117 = 5/72

To isolate the variable, we can cross-multiply: x/117 = 5/72 72 * x = 117 * 5 72x = 585

Dividing both sides by 72: 72x/72 = 585/72 x = 585/72

Simplifying the fraction: x = 65/8.
