Question

Repartir s/1400 en partes proporcionales a las proporcionales a 5, 9, 10 y 12 ​

Answer 1

Las partes repartidas son:

194,44

350

388,89

467,67

I)

5k + 9k + 10k + 12k = 1400

36k = 1400

k = 38,88

5(38,88) = 194,44

9(38,88) = 350

10(38,88) = 388,89

12(38,88) = 467,67

II)

x/5 ; y/9 ; z/10 ; m/12

x + y + z + m / 5 + 9 + 10 + 12

1400 / 36

x/5 = 1400/36

36x = 5(1400)

36x = 7000

x = 194,44

y/9 = 1400/36

36y = 1400(9)

y = 350

z/10 = 1400/36

36z = 14 000

z = 388,89

m/12 = 1400/36

36m = 1400(12)

m = 466,67
