Summaation of a sequence

or see a smaller scale
from 1 to 10
notice
1+10=11
2+9=11
etc
5+6=11
10/2=5
there are 5 pairs
5*11=55

so

1 to 100
1+100=101
2+99=101
...
50+51=101

100/2=50
there ar 50 pairs
50 times 101=5050

the sum is 5050

Is 12/50 Grader than 4/5

Oliga [24]

Answer:

No, $\frac{4}{5}$ is greater than $\frac{12}{50}$ .

Step-by-step explanation:

The two fractions to be compared are given as:

$\frac{12}{50}$ and $\frac{4}{5}$

Now, in order to compare them, we need to make the denominator same for both the fractions and then compare their numerators.

LCD of 50 and 5 is 100. So, we try to make each denominator 100 and change the numerator accordingly.

We multiply the first fraction by $\frac{2}{2}$ and we multiply the second fraction by $\frac{20}{20}$ as given below:

$\frac{12\times 2}{50\times 2}=\frac{24}{100}\\\frac{4\times 20}{5\times 20}=\frac{80}{100}$

Now, the two new fractions are $\frac{24}{100}$ and $\frac{80}{100}$ .

Now, we check the numerators. The numerator that is larger among the two has the greater fraction value.

Here, 80 is greater than 24. So, fraction $\frac{80}{100}$ is greater than $\frac{24}{100}$ or $\frac{4}{5}$ is greater than $\frac{12}{50}$ .
