Answer:
1. 9[tex]\frac{1}{11}[/tex]%
2. 0.45
3. 98.5%
4. 80%
5. Decimal: 0.15, Fraction: [tex]\frac{3}{20}[/tex]
Step-by-step explanation:
When calculating percentage, turn the question to a fraction and multiply the fraction by 100%.
When calculating decimal, turn the question to a fraction out of 100, and turn it into a decimal.
When calculating a fraction in its simplest form, turn the question to a fraction and simplify it.
1. (Percentage)
Fraction: [tex]\frac{1}{11}[/tex]
Percentage: [tex]\frac{1}{11}[/tex] × 100% = 9[tex]\frac{1}{11}[/tex]%
2. (Decimal)
Fraction: [tex]\frac{45}{100}[/tex]
Decimal: 45 ÷ 100 = 0.45
3. (Percentage)
Fraction: 0.985 = [tex]\frac{985}{1000}[/tex]
Percentage: [tex]\frac{985}{1000}[/tex] × 100% = 98.5%
4. (Percentage)
Fraction: [tex]\frac{4}{5}[/tex]
Percentage: [tex]\frac{4}{5}[/tex] × 100% = 80%
5. (Decimal)
Fraction: 15% = [tex]\frac{15}{100}[/tex]
Decimal: 15 ÷ 100 = 0.15
5. (Fraction)
Fraction: [tex]\frac{15}{100}[/tex]
Simplest form: [tex]\frac{15}{100}[/tex] = [tex]\frac{3}{20}[/tex] (Divide both numerators and denominators by 5)
