Question

sa se imaprta numarul 555 in parti invers proportionale cu numerele 5 6 si 4

Answer 1

Răspuns:

{a, b, c} i.p. {5, 6, 4}

a = k/5

b = k/6

c = k/4

a + b + c = 555

k/5 + k/6 + k/4 = 555  / x 60

12k + 10k + 15k = 33300

37k = 33300

k = 33300 : 37

k = 900

a = k/5 = 900/5 = 180

b = k/6 = 900/6 = 150

c = k/4 = 900/4 = 225
