CorrectNot quiteAnswer A

Correct answer: A

'Of' first: $\frac{3}{5} \times 75 = 45$ .
Division and multiplication left to right: $18 \div 3 = 6$ , $6 \times 2 = 12$ .
Then $45 - 12 + 4 = 37$ .

Worth noting

Multiplying $3 \times 2$ first gives $18 \div 6 = 3$ and the answer 46; forgetting the $\times 2$ gives 43.

Concept: Combining 'of', left-to-right division and multiplication, and signs
