Answer:
20
Step-by-step explanation:
Let [tex]x[/tex] = the number of problems Anna completed
Using ratios
5 : 8 = [tex]x[/tex] : 32
[tex]\frac{5}{8} =\frac{x}{32}[/tex]
Cross multiply: 5 x 32 = [tex]x[/tex] x 8
160 = 8[tex]x[/tex]
Divide both sides by 8: 20 = [tex]x[/tex]
Therefore, Anna completed 20 problems.
