Answer:
3,524 corresponde al fraccionario 
.
Step-by-step explanation:
La coma está desplazada tres espacios (3 dìgitos) hacia la izquierda del observador, el número decimal tiene su equivalente forma fraccionaria, en donde el numerador son todos los dìgitos en series y el denominado tiene la forma 10ⁿ, donde n es la cantidad de espacios que ha sido desplazada la coma. Entonces, 3,524 tiene la siguiente expresión:
3,524 corresponde al fraccionario .

Step-by-step explanation:
Given : the hydronium ion concentration is 
in orange juice
To Find: what is the pH?
Solution :
Definition of pH : pH is the negative log of the molar hydrogen ion concentration
Formula of pH : - log [H+]
Since we are given H+ =
So, substituting this value in formula :
![pH = - log [3.4*10^{-4}]](https://tex.z-dn.net/?f=pH%20%3D%20-%20log%20%5B3.4%2A10%5E%7B-4%7D%5D)
![pH = - log [3.4*0.0001]](https://tex.z-dn.net/?f=pH%20%3D%20-%20log%20%5B3.4%2A0.0001%5D)
![pH = - log [0.00034]](https://tex.z-dn.net/?f=pH%20%3D%20-%20log%20%5B0.00034%5D)
pH = 3.468≈3.5
Thus the pH is 3.5
Answer:
You divide each fraction by the highest multiple.
4/16 can be divided by 4 to get 1/4
12/18 can be divided by 6 to get 2/3
4/10 can be divided by 2 to get 2/5
16/20 can be divided by 4 to get 4/5
Step-by-step explanation:
hope this helps
Because the left side is eclipsed in an absolute value, we have two possible values of x, denoted by:
2x+4 = 12 and -(2x+4) = 12
Solving for both of these, we are presented with the two values of x:
x = 4 and x = -8
