- AQ, P, S, R
- BS, P, Q, R
- CP, Q, S, R
- DR, Q, P, S
Step-by-Step Solution
Write each with denominator 12: P , Q , R , S . Smallest first: , i.e. S, P, Q, R. Note that the minus sign on Q's denominator still makes it negative.
Answer: B) S, P, Q, R
Arrange the rational numbers on the four cards in ascending order (smallest first).

Key idea: Recognising rationals
If you can write a number as **integer over non-zero integer**, it is rational. So:
- All integers are rational: 5 = 5/1, 0 = 0/1, −9 = −9/1.
- All fractions with integer numerator and denominator are rational: 3/4, −2/7, 11/3.
- Any decimal that terminates or repeats is rational: 0.25 = 1/4, 0.333… = 1/3.
Numbers that cannot be written as p/q (like √2 or π) are NOT rational — they're irrational. You'll meet those in Class 9.
