cum27*a=45*b => 27*a /b=45 =>a/b=45/27
dar a/b=x/36 =>
=>45/27=x/36=> 45*36=27*x=> x=45*36/27 =5*12=60
dar a/b=x/36 =>
=>45/27=x/36=> 45*36=27*x=> x=45*36/27 =5*12=60
stii ca a si b sunt numere naturale si
27a=45b
iar [tex] \frac{a}{b} [/tex]=[tex] \frac{x}{36} [/tex]
si ai astfel
27*a=45*b=>[tex] \frac{a}{b} [/tex]=[tex] \frac{45}{27} [/tex] si egalezi si cu ce stii din ipoteza
adica
[tex] \frac{a}{b} [/tex]=[tex] \frac{45}{27} [/tex]=[tex] \frac{x}{36} [/tex]
=>27x=45*36
=>x=[tex] \frac{45*36}{27} [/tex]
efectuezi calculul si astfel vei avea x=60
27a=45b
