Concept:A ratio divides a total amount into equal-sized parts, so the largest share is the fraction of the total corresponding to the largest ratio number.Explanation:Total amount = ₦10.50Given ratio = $6 : 7 : 8$Add the ratio parts to find the total number of shares:$6 + 7 + 8 = 21$The largest ratio part is $8$, so the largest share is the fraction $\frac{8}{21}$ of the total amount.Largest share = $\frac{8}{21} \times \text{N}10.50$Since $10.50 \div 21 = 0.50$, the share is $8 \times 0.50 = 4.00$So the largest share = ₦4.00.Answer:₦4.00Option B.
