Question

Реши уравнение: 1,22⋅y=1,23.

помогите пожалуйста

Answer 1

$1.22y = 1.23$

Поскольку

$a \times b = c < = > b = c \div a$

равноправно, то

$y = \frac{1.23}{1.22}$

$y ≈ 1.0082$

Answer 2

$1,22*y=1,23;\\y=1,23:1,22;\\y=\dfrac{123}{100} :\dfrac{61}{50} ;\\y=\dfrac{123}{100} *\dfrac{50}{61} ;\\y=\dfrac{123}{2} *\dfrac{1}{61} ;\\y=\dfrac{123}{122} =1\dfrac{1}{122} .$
