1
In this lesson, I'm going to talk about how to simplify fractions.
2
So let's start with a basic example, 6 over 8.
3
How can we simplify this fraction?
4
Well, notice that 6 and 8 are both even numbers.
5
So therefore, we can divide each number by 2.
6
6 divided by 2 is 3.
7
8 divided by 2 is 4.
8
And so the answer is going to be 3 over 4.
9
Now what about 8 over 12?
10
How can we simplify that fraction?
11
So 8 and 12 are even numbers, so we can divide each number by 2.
12
8 divided by 2 is 4, 12 divided by 2 is 6.
13
Now we still have even numbers, so we can divide it by 2 again.
14
4 divided by 2 is 2, 6 divided by 2 is 3.
15
so the answer is 2 over 3.
16
Another way in which you can do that problem is you could realize
17
that 8 is basically 4 times 2 and 12 is 4 times 3
18
and so you can cancel 4 and then this will give you the final result of 2 over 3.
19
For the sake of practice go ahead and try these two examples 15 over 24 and 35 over 49
20
go ahead and simplify those two fractions 15 is 5 times 3 24 is 8 times 3
21
so we could cancel a 3 and
22
so the final answer for the first example it's going to be 5 over 8
23
Now let's move on to the next example.
24
What do you know about 35 and 49?
25
35 and 49 have a common number that goes into both of them, and that is 7.
26
35 is 7 times 5.
27
49 is 7 times 7.
28
And so we could cancel a 7, giving us the answer 5 over 7.
29
Try these two.
30
48 over 72 and also 38 over 57.
31
Now 48, what two numbers do you think is equal to 48?
32
The first two numbers that come in my mind are 8 and 6.
33
And 72 is 9 times 8 or 8 times 9.
34
So we could cancel on 8.
35
Now we could still simplify this further.
36
6 is 3 times 2.
37
9 is 3 times 3.
38
And so these can be cancelled.
39
Thus the final answer for that problem is 2 over 3.
40
Now what about 38 and 57?
41
Both numbers are divisible by 19.
42
19 times 2 is 38.
43
19 times 3 is 57.
44
And once again, the final answer is 2 over 3.
45
So now you know how to simplify fractions.

¿Qué es la Técnica de Shadowing?

Shadowing es una técnica de aprendizaje de idiomas respaldada por la ciencia, desarrollada originalmente para la formación de intérpretes profesionales y popularizada por el políglota Dr. Alexander Arguelles. El método es simple pero poderoso: escuchas audio en inglés nativo y lo repites en voz alta de inmediato, como una sombra que sigue al hablante con solo 1-2 segundos de retraso. A diferencia de la escucha pasiva o los ejercicios de gramática, el shadowing obliga a tu cerebro y músculos de la boca a procesar y reproducir simultáneamente patrones de habla reales. Las investigaciones muestran que mejora significativamente la precisión de la pronunciación, la entonación, el ritmo, el habla conectada, la comprensión auditiva y la fluidez al hablar, convirtiéndola en una de las metodologías más efectivas para la preparación del IELTS Speaking y la comunicación en inglés en el mundo real.
