This might be confusing so I am adding an explanation here.
1) convert ratios to fractions first, then convert fractions to same denominator.
2) boys = girls + 2048. So when looking at fiction books borrowed by boys, think of it as 1/4 girls + 1/4*2048.
3) draw model to compare fiction books borrowed by boys and girls and you should see that 7units represent 812. Do the calculations from there to find total books borrowed.
Let me know if you have any questions, I will be happy to help!
