BECE Mathematics 2022 Paper

Concept:To undo a division by $100$, multiply both sides of the equation by $100$.Solution:$\dfrac{n}{100} = 10.5$Multiply both sides by $100$:$n = 10.5 \times 100$Multiplying by $100$ moves the decimal point two places to the right:$n = 1050$Check: $\dfrac{1050}{100} = 10.5$ ✓Key point: Here $n$ is divided by $100$, so $n$ must be larger than $10.5$. Answers like $0.105$ come from dividing $10.5$ by $100$ instead of multiplying.Answer:Option D ($1050$)
