[tex] \frac{?}{?} = \frac{?}{?} = \frac{?}{?} [/tex]
a/3 = b/4 = c/5 ve a + b - c = 12 olduğuna göre b kaçtır?​

Sagot :

a ve c yi b cinsinden bulalım

[tex]\frac{a}{3} = \frac{b}{4}[/tex]

içler dışlar yapalım

[tex]4a = 3b\\a = \frac{3b}{4}[/tex] a yerine bunu yazacağız

c yi bulalım

[tex]\frac{c}{5} = \frac{b}{4}[/tex]

Şimdi yerlerine yazalım

[tex]\frac{3b}{4} -\frac{5b}{4} +b = 12 \\ \\3b=12\\b=4[/tex]
