Estoy haciendo Numeros reales e irracionales y hay un ejercicio que dice “expressa como fracción aquellos que sean posibles” 4,2= 42-4/9= 38/9 mi pregunta es de donde sale el 9 no lo entiendo.

120 seems like the most sensible answer.

step-by-step explanation:

if there is only one topping on all caramel apples and there's 120 of them. then all apples should/will be covered in sprinkles. make sense?

12r - 8 - 12

you have to combine like terms. below i have bolded the like terms:

12r - 8 - 12

together it combines to:

12r - 20

hope this !
