Answer:
Step-by-step explanation:
We can set up the following equation:
[tex]\frac{80}{100} = \frac{36}{N}[/tex]
where [tex]N[/tex] is the total number of shapes on Abigail's paper.
Let's first multiply both sides by [tex]N[/tex]:
[tex]\frac{80N}{100} = 36[/tex]
Next, let's multiply both sides by [tex]100[/tex]:
[tex]80N = 3600[/tex]
Finally, let's divide both sides by [tex]80[/tex]:
[tex]N = 45[/tex]
