Which expression represents rational numbers? Select all that apply

Vladimir79 [104]

Answer:

1. $\sqrt{100} \sqrt{100}$

2. 13.5 + $\sqrt{81}$

3. $\sqrt{9} + \sqrt{729}$

6. $\frac{3}{5} + 2.5\\\frac{3+12.5}{5}\\\frac{15.5}{5}\\= 3.1$

These four options are rational;

Step-by-step explanation:

1. $\sqrt{100} \sqrt{100}$ equals to 10 * 10 = 100 which is rational

2. 13.5 + $\sqrt{81}$ equals 13.5 + 9 = 22.5

3. $\sqrt{9} + \sqrt{729}$ -- 3+27 = 30

6. $\frac{3}{5} + 2.5\\\frac{3+12.5}{5}\\\frac{15.5}{5}\\= 3.1$

Option 4 and 5 are irrational because they include $\sqrt{353}$ and $\sqrt{216}$ which are not a perfect square and their answers will be non recurring and non terminating decimal fraction.

una fracion reducicion a su minima expresion en igual a 1/8 . si la suma de sus terminos es 72. hallar la diferencia entre ellos

Mandarinka [93]

La diferencia entre el denominador y el númerador de la fracción es:

64 - 8 = 56.

<h3>¿Como encontrar la fracción?</h3>

Tendremos una fracción de la forma:

$\frac{a}{b}$

Tal que:

$\frac{a}{b} = \frac{1}{8}$

$a + b = 72$

Eso es un sistema de ecuaciones

Primero, podemos reescribir la primer ecuación como:

$8a = b$

Ahora podemos reemplazar "b" en la segunda ecuación por "8a", así obtenemos:

$a + 8a = 72\\\\9a = 72\\\\a = 72/9 = 8$

Ahora podemos obtener el valor de b:

$b = 8a = 8*8 = 64$

La diferencia entre a y b es:

$b - a = 64 - 8 = 56$
