1.	Which of the following rule do we apply while subtracting the given rational number i.e. p/q and r/s?1. (ps – qr)/qs2. (pr – qr)/qs3. (pq – rs)/qs4. (ps – qs)/qr
Answer» Correct Answer - Option 1 : (ps – qr)/qs Concept: The LCM of two variables can be found using multiplying two variables. Calculation: Given: Subtract p/q and r/s p/q - r/s Taking LCM of q and s, that is, multiplying them, we get (ps - qr)/qs Hence, we conclude that by subtracting p/q and r/s, we get (ps - qr)/qs.

Answer» Correct Answer - Option 1 : (ps – qr)/qs

Concept: The LCM of two variables can be found using multiplying two variables.

Calculation:

Given: Subtract p/q and r/s

p/q - r/s

Taking LCM of q and s, that is, multiplying them, we get

(ps - qr)/qs

Hence, we conclude that by subtracting p/q and r/s, we get (ps - qr)/qs.
