CorrectNot quiteAnswer C

Correct answer: C

Explanation

  1. 'Of' is done before division: 13\frac{1}{3} of 36=1236 = 12.

  2. Then 540÷12=45540 \div 12 = 45.

Worth noting

Dividing first gives 540÷13=1620540 \div \frac{1}{3} = 1620, then 1620×36=583201620 \times 36 = 58320. In BODMAS the O stands for 'of', which ranks above division.
