Need help please, and thank you

Answer:
The percent of pages Jace read at school is [tex]\frac{3}{20}[/tex] × 100 = 15%
The percent of pages Jace need to read at home is 100% - 15% = 85%
Step-by-step explanation:
Scale 1: One division represents 100% ÷ 20 divisions = 5%
Scale 2: One division represents 20 pages ÷ 20 divisions = 1 page
The proportion that can be used to determine the percentage of pages Jace read at school is 3 out 20 pages = [tex]\frac{3}{20}[/tex]
Jace need to read 20 - [tex]\frac{3}{20}[/tex] = [tex]\frac{17}{20}[/tex] pages at home.
That is [tex]\frac{17}{20}[/tex] × 100 = 85%
