Cual es la simplificacion de 66/81

Karo-lina-s [1.5K]

Answer:

Hence the simplification of $\dfrac{66}{81}$ is $\dfrac{22}{27}$

Step-by-step explanation:

<em>" Simplification is the process of replacing a mathematical expression by an equivalent one, that is simpler (usually shorter), </em>

<em>for example</em><em>: Simplification of a fraction to an irreducible fraction ". </em>

Here we are given a fraction as:

$\dfrac{66}{81}$

As both the numerator and denominator are divisible by a factor of 3 hence we take out the common factor and obtain the reduced fraction which is further irreducible.

As 66=3×22 and 81=3×27

Hence $\dfrac{66}{81}=\dfrac{3\times22}{3\times27}=\dfrac{22}{27}$

Hence the simplification of $\dfrac{66}{81}$ is $\dfrac{22}{27}$

Write a quadratic function in vertex form whose graph has the vertex (−5, −1) and passes through the point (−2, 2)

fenix001 [56]

$f(x) = a(x+5)^2-1$

$2 = a(-2+5)^2-1 \\ 9a = 3 \\ a = 3$

$f(x) = 3(x+5)^2-1$

Yellowstone National Park is a popular field trip destination. This year the senior class at High School A and the senior class

Rina8888 [55]

Each van carries 13 students and each bus carries 25 students.

<h3><u>Distribution</u></h3>

Given that the senior class at High School A and the senior class at High School B both planned trips to Yellowstone, and the senior class at High School A rented and filled 5 vans and 2 buses with 115 students, while High School B rented and filled 1 van and 6 buses with 163 students, and each van carried the same number of students and each bus carried the same number of students, to determine the number of students in each van and in each bus, the following calculation must be made:

5X + 2Y = 115
1X + 6Y = 163
5X + 2Y = 115
5X + 30Y = 815
815 - 115 = 28Y
700 = 28Y
Y = 700 / 28
y = 25
1X + 6x25 = 163
1X = 163 - 150
X = 13

Therefore, each van carries 13 students and each bus carries 25 students.

The number 1.3,1/1/3,1.34 in least to greatest

elixir [45]

1.3, 1 1/3, 1.34

The decimal version of 1 1/3 is 1.333 (so on)

so 1.3 is less than 1.333 and 1.333 is less than 1.34

1.3<1.333<1.34
