Marks: 1
Concept: Make denominators same (LCM 8). Add numerators.

2. $\frac{5}{6} - \frac{1}{3} = \frac{5}{6} - \frac{2}{6} = \frac{3}{6} = \frac{1}{2}$
Marks: 1
Concept: Convert $\frac{1}{3}$ to sixths, subtract, simplify.

3. $\frac{2}{5} \times \frac{3}{7} = \frac{2 \times 3}{5 \times 7} = \frac{6}{35}$
Marks: 1
Concept: Multiply numerators and denominators.

4. $\frac{1}{2} \div 3 = \frac{1}{2} \times \frac{1}{3} = \frac{1}{6}$
Marks: 1
Concept: Dividing by whole number = multiply by reciprocal.

5. $4 \div \frac{1}{2} = 4 \times 2 = 8$
Marks: 1
Concept: "How many halves in 4?" = 8.

6. $\frac{3}{4} \div \frac{1}{2} = \frac{3}{4} \times 2 = \frac{6}{4} = 1\frac{1}{2}$
Marks: 1
Concept: Multiply by reciprocal of $\frac{1}{2}$ (which is 2).

7. Left = $1 - \frac{3}{8} = \frac{5}{8}$
Marks: 1
Concept: Whole cake = $\frac{8}{8}$ .

8. $\frac{9}{12} = \frac{3}{4}$ (divide by 3)
Marks: 1
Concept: Simplify by greatest common divisor.

9. $\frac{2}{3} \times 24 = 16$
Marks: 1
Concept: "of" means multiply.

10. $\frac{2}{5} = 0.4, \frac{1}{2}=0.5, \frac{3}{4}=0.75$ → $\frac{2}{5}, \frac{1}{2}, \frac{3}{4}$
Marks: 1
Concept: Compare by decimal or common denominator.

Section B

11. $\frac{3}{5} - \frac{1}{4} = \frac{12}{20} - \frac{5}{20} = \frac{7}{20}$ kg
Marks: 2 (1 for common denom, 1 for answer)
Concept: Subtract fractions of same whole (kg).

12. Used $\frac{1}{3}$ of full tank; remaining = $1 - \frac{1}{3} = \frac{2}{3}$ (note: tank had $\frac{7}{8}$ but used based on full capacity).
Marks: 2
Concept: Fraction of full capacity, not of current water.

13. $6 \div \frac{2}{3} = 6 \times \frac{3}{2} = 9$ ribbons. Means 9 pieces of $\frac{2}{3}$ m fit in 6 m.
Marks: 2 (1 calc, 1 context)
Common mistake: saying 4.

14. $2\frac{1}{2} = \frac{5}{2}$ ; $\frac{5}{2} \times \frac{3}{4} = \frac{15}{8} = 1\frac{7}{8}$
Marks: 2
Concept: Convert mixed number to improper fraction.

15. Boys = $\frac{3}{8} \times 40 = 15$ ; girls = $40 - 15 = 25$
Marks: 2
Concept: Find fraction then subtract from whole.

16. $\frac{2}{7} + \frac{3}{14} = \frac{4}{14} + \frac{3}{14} = \frac{7}{14} = \frac{1}{2}$
Marks: 2
Concept: Common denominator 14.

Section C

17. Let original = $x$ . Spent book: $\frac{1}{3}x$ , remainder $\frac{2}{3}x$ . Spent pen: $\frac{1}{4} \times \frac{2}{3}x = \frac{1}{6}x$ . Left: $x - \frac{1}{3}x - \frac{1}{6}x = \frac{1}{2}x = 30$ → $x = 60$ .
Marks: 3 (1 remainder, 1 second spend, 1 answer)
Concept: Track changing remainders.

18. Peter $x$ , Mary $720-x$ . Peter left: $x \times \frac{4}{7} \times \frac{3}{4} = \frac{3}{7}x$ . Mary left: $(720-x) \times \frac{3}{5}$ . Equal: $\frac{3}{7}x = \frac{3}{5}(720-x)$ → $15x = 7(2160-3x)$ ? Actually multiply by 35: $15x = 21(720-x)$ ? Let's do: $\frac{3}{7}x = \frac{2160-3x}{5}$ → $15x = 15120 - 21x$ → $36x=15120$ → $x=420$ .
Marks: 3 (1 setup, 1 solve, 1 answer)
Concept: Model or algebra; same final amount.

19. First gets $\frac{1}{2}$ , remainder $\frac{1}{2}$ . Second gets $\frac{1}{3} \times \frac{1}{2} = \frac{1}{6}$ . Total given = $\frac{1}{2}+\frac{1}{6}=\frac{2}{3}$ . Third gets $\frac{1}{3}$ = 8 → total = 24.
Marks: 3
Concept: Remainder fraction of remainder.

20. $5 \div \frac{3}{4} = 5 \times \frac{4}{3} = \frac{20}{3} = 6\frac{2}{3}$ . So 6 full batches, $\frac{2}{3}$ of a batch left (or $\frac{2}{3} \times \frac{3}{4} = \frac{1}{2}$ cup? but q asks fraction of batch).
Marks: 3 (1 calc, 1 full, 1 fraction)
Concept: Division yields mixed number.
