Question

Daca a×5=b×10 ,atunci b÷a ?

Answer 1

Explicație pas cu pas:

a×5=b×10

$\frac{b}{a} = \frac{5}{10} \iff \frac{b}{a} = \frac{1}{2} \\ \implies b : a = \frac{1}{2}$

Answer 2

Răspuns:

Rezolvare a

$a \times 5=b \times 10$

$5a=10b$

$\frac{5a}{5}=\frac{10b}{5}$

$a=\frac{10b}{5}$

$a=2b$

Rezolvare b

$a \times 5=b \times 10$

$b\times 10=a\times 5$

$10b=5a$

$\frac{10b}{10}=\frac{5a}{10}$

$b=\frac{5a}{10}$

$b=\frac{a}{2}$

Rezultatul⬇️

$= > b \div a = \frac{1}{2}$
