Since 3/4 of Yvonne = 2/7 of Zaid,

we make the numerator the same so that the number of units is the same.

3/4 = 6/8
2/7 = 6/21

So this means Yvonne has 8 units and Zaid has 21 units.

Ratio = 8 : 21


21 units - 8 units = 13 units

Yvonne had 13 units fewer than Zaid.

13 units = 91 files
1 unit = 91 files ÷ 13 = 7 files

Files they have altogether
= 8 units + 21 units
= 29 units
= 29 x 7 files
= 203 files
