Question

Как решить пропорцию "y : 1.8 = 0.2 : y"?

Answer 1

Умножение средних членов, равно умножению крайних членов.

Answer 2

Так и решить
y/1,8 = 0,2/y
Перемножаем крест накрест
y^2 = 1,8*0,2 = 0,36
y = 0,6

Answer 3

I can help you with your question.

To solve the proportion "y : 1.8 = 0.2 : y", you need to cross-multiply the terms and then isolate y. Here are the steps:

- Cross-multiply: $$y \times y = 1.8 \times 0.2$$ - Simplify: $$y^2 = 0.36$$ - Take the square root of both sides: $$y = \pm \sqrt{0.36}$$ - Simplify: $$y = \pm 0.6$$

The final answer is $$y = \pm 0.6$$, which means that y can be either 0.6 or -0.6.Ответь+подробно.+Как+решить+пропорцию+"y+:+1.8+=+0.2+:+y"?
