Question

impartiti numarul 235 in 2 nr eglale astfer la cele 2 parti sa se afle in raportul 2 pe 3

Answer 1

a + b = 235

a/b = 2/3

a = 2b/3

2b/3 + b = 235 /x3

2b + 3b = 705

5b = 705

b = 705 : 5 = 141

a = 141 x 2 / 3 = 282/3 = 94

94 + 141 = 235

94/141 = 2/3

II varianta :

2 + 3 = 5 parti

235 : 5 = 47

47 x 2 = 94

47 x 3 = 141

94/141 = 2/3

94 + 141 = 235

Answer 2

$\frac{a}{b} = \frac{2}{3} \\ \\ a + b = 235 \\ \\ a = \frac{2b}{3} \\ \\ \frac{2b}{3} + b = 235 \\ \\ 2b + 3b = 705 \\ \\ 5b = 705 \\ \\ b = 141 \\ \\ a = \frac{2 \times 141}{3} = 94$
