Step13: Fix fraction/decimal for 40%

Percent to decimal: $40\% = 0.40$; reduced fraction: $\frac{2}{5}$

Step14: Fix fraction/decimal for 50%

Percent to decimal: $50\% = 0.50$; reduced fraction: $\frac{1}{2}$

Step15: Fix fraction/decimal for 60%

Percent to decimal: $60\% = 0.60$; reduced fraction: $\frac{3}{5}$

Step16: Fill fraction/decimal for 70%

Percent to decimal: $70\% = 0.70$; decimal to fraction: $\frac{7}{10}$

Step17: Fill fraction/decimal for 80%

Percent to decimal: $80\% = 0.80$; reduced fraction: $\frac{4}{5}$

Step18: Fill fraction/decimal for 90%

Percent to decimal: $90\% = 0.90$; decimal to fraction: $\frac{9}{10}$
