If the problem is referring to the equivalent logarithmic equation log (20 *27).
We can easily find and solve its equivalent expression using one of the many identities available in logarithmic. 
We can have the expression:
log (20*27) = log 20 + log 27

The sum of three times a number and 4 is between -8 and 10
Alex
Alright, so we can start by writing it out by their signs.
Using PEMDAS (Parenthesis, Exponent, Multiplication, Division, Addition, Subtraction) and noting that the inequality comes last, we can write it as the sum of (addition), then three times (multiplication) a number and 4 (ties in with the sum of, making it also addition).Note that we know that "a number and 4" means addition because it doesn't state to do anything with it, and we don't know what "the sum of" referred to with numbers, so they match up. Therefore, we have multiplication (3 times a number=3 * number), then addition (3 times a number, or 3 * number, added to 4, or 3*number+4), and we can do the inequality. Between -8 and 10 means that it is greater than -8 and less than 10, as 10 is the larger number, writing it out as -8< (less than) 3*number+4 < (3*number+4 is less than 10, so we have another less than sign) 10. Subtracting 4 from everything using the subtraction property of equality, we get -12<3*number<6. Next, we can divide everything by 3 to separate the number and get -4<number<2.

Hola me ayudan con esta pregunta TRANSFORMAR LOS SIGUIENTES DECIMALES EN FRACCIÓN, 1.- 8,485 2.- 125,65 3.- 54,987987... 4.- 266

Step-by-step explanation:

Para hacer la conversión de decimales a fracción, es necesario hacer dos cosas:

1. Identificar el tipo de decimal (finitos, infinito periódico, infinito semi periódico).

2. Aplicar la expresión o formula correspondiente, dependiendo del tipo de decimal.

Un decimal finito es aquel que solo tiene un número determinado de decimales y no se extiende al infinito.

Un decimal infinito periódico, es aquel cuya cifra decimal se repite constantemente hasta el infinito, esto puede ser un decimal, dos, etc.

Un decimal semi infinito periódico es aquel donde una parte de los decimales se mantiene sin repetir, y la otra parte se repite hasta el infinito.

Una vez que hayas identificado el tipo de decimal, solo debes aplicar alguna de los 3 casos siguientes:

1. PAra un decimal finito se convierte la cifra decimal en un numero entero multiplicando por 10, 100, 1000 depende del número de decimales que tenga, y se divide entre 10, 100, 1000.... segun el número de decimales y se simplifica la fracción si es posible.

2. Para un infinito periódico se anota el número y se le resta él o los números que están antes del período. Se coloca como denominador un 9 por cada número que está en el período (si hay un número bajo la rayita se coloca un 9, si hay dos números bajo el período se coloca 99, etc.). Si se puede simplificar, se simplifica.

3. El numerador de la fracción se obtiene, restando al número la parte entera y el anteperíodo, o sea, todo lo que está antes de la “rayita”.  El denominador de la fracción se obtiene colocando tantos 9 como cifras tenga el período y tantos 0 como cifras tenga el anteperíodo. Como siempre, el resultado se expresa como fracción irreductible (no se puede simplificar más) o como número mixto.

Dicho esta parte teórica, pasemos a la práctica y convirtamos los decimales a fracción:

1. 8,485: decimal finito, con 3 decimales, lo anotamos sin la coma, y entonces colocas como denominador el 1000, porque fueron 3 decimales, 3 ceros ----------> 8485/1000 = 1697/200   (se simplificó por 5)

2.  125,65: decimal finito -----> 12565/100 = 2513/20

3. 54,987987: infinito periódico, aplicamos los pasos de arriba:

54,987987 = 54987 - 54 / 999 = 54933 / 999

4. 266.8484..: infinito periódico

266,8484.... = 26684 - 266 / 99 = 26418 / 99

5. 4,78999.: Infinito semiperiódico

4,78999 = 4789 - 478 / 900 = 4311 / 900

6. 942,74111: infinito semiperiódico

942,74111 = 942741 - 94274 / 900 = 848467 / 900
