Answer 2

Answer:

So, the fractions can't be compared by just looking at their numerators or denominators, because that doesn't give us the correct answer.

So, I can solve your question in two ways.

1st way

You can simply divide the numerator by the denominator.

Like, you can divide 1 by 5 which will give 0.2.

And further, dividing 2 by 7 will give 0.2857142857.

And dividing 7 by 10 will give 0.7.

So, $\frac{1}{5}=0.2 \frac{2}{7}= 0.2857142857 \frac{7}{10}=0.7 \\ \therefore data in descending order can be \frac{7}{10}, \frac{2}{7} and \frac{1}{5}$

2nd way

So, lets take an example.

You know, when there is a boxing match, then, players are taken according to their weight(weight category). No two players combat with each other, by having different weight.

Accordingly, here, denominators are the weight of the fractions, which needs to be equal so as to compare them.

So, an easy way is to just multiply the denominators by their L.C.M. i.e. 100.
