Número Recionales
x l x en un cociente de dos enteros con denominador distinto de 0
Propiedad fundamental:cuando un número racional esra en su mínima expresiós
Si a, b y K son enteros con b ≠ 0 y K ≠ 0, entonces (a∙k)/(b∙k)=a/b
36/54 = 2 ∙ 18/ 3∙18 = 2/3
Metodos de productos cruzados
Para los números a/b y c/d, b ≠ 0, d ≠ 0,
36/54=(2∙18)/(3∙18)=2/3 - 36∙ 3= 108 =54∙ 2
Suma y sustracción de números racionales
Si a /b y c/d son números racionales
2/15 + 1/10 = 4/30 + 3/30 = 7/30
a/b + c/d = (ad) + (bc) /bd y a/b - c/d = ad- bc /bd
Multiplicación
Si a/b y c/d son racionales, entonces a/b ∙ c/d =ac/bd
3/4∙7/10 = 3∙7/4∙10 = 21/40
División
Si a/b y c/d son números racionables, donde c/d ≠ 0 entonces, a/b ÷ c/d = a/b ∙ d/c =ad/bc
3/5 ÷ 7/15 = 3/5 ∙ 15/7 = 45/35 = 9∙5 /7∙5 =9/5
