Finding the Difference between the Largest and Smallest Share in a Ratio Division Problem

The video tutorial explains how to calculate the difference between the largest and smallest shares when ¥3450 is divided in the ratios 2/6 and 7. It involves adding the ratios to find the total parts, calculating the value of one part, and then determining the difference in parts between the largest and smallest shares. The final calculation is done by multiplying the difference in parts by the value of one part, resulting in ¥1170. The tutorial also outlines the marking scheme for the problem.
