[]/[] > []/[], if p × s > r × q
Given that p/q and r/s are two rational numbers with different denominators and both of them are in standard form. To compare these rational numbers we say that:

Solution:

Given, p/q and r/s are two rational numbers with different denominators.

p/q and r/s are in standard form.

We have to fill in the boxes if p × s > r × q

From the given statement,

p × s > r × q

On simplification,

p/q > r/s

Therefore, p/q > r/s

✦ Try This: Write the following number in the form p/q , where p and q are integers : opposite

of 4

Given, p and q are integers

We have to write the opposite of 4 in the form of p/q.

Opposite of 4 means reciprocal of 4.

Reciprocal means an expression which when multiplied by another expression, gives unity (1) as a result.

Reciprocal of 4 = 1/4

Therefore, p/q = 1/4
