BECE Mathematics 2025 Paper

Concept:To find $y$, divide both sides by $0.03$. Multiply top and bottom by 100 to clear the decimals before dividing.Solution:$0.03 \times y = 2.4$Divide both sides by $0.03$: $y = \dfrac{2.4}{0.03}$Multiply top and bottom by 100: $y = \dfrac{2.4 \times 100}{0.03 \times 100} = \dfrac{240}{3}$$y = 80$Check: $0.03 \times 80 = 2.40$ ✓Key point: Multiplying only the top (or only the bottom) by 100 gives $8$ or $0.8$; both must be multiplied by the same number.Answer:Option D ($80.0$)
