Question 90 (c)
Given that,pq and rs are two rational numbers with different denominators and both of them are in standard form. To compare these rational numbers, we say that ☐☐<☐☐, if p×s>r×q
Given, p×s>r×q ⇒pq>rs [by transferring sides]
Question 90 (a)
Given that, pq and rs are two rational numbers with different denominators and both of them are in standard form. To compare these rational numbers, we say that ☐☐<☐☐, if p×s<r×q
