Answer 2

Answer:

1. 9$\frac{1}{11}$%

2. 0.45

3. 98.5%

4. 80%

5. Decimal: 0.15, Fraction: $\frac{3}{20}$

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: $\frac{1}{11}$

Percentage: $\frac{1}{11}$ × 100% = 9$\frac{1}{11}$%

2. (Decimal)

Fraction: $\frac{45}{100}$

Decimal: 45 ÷ 100 = 0.45

3. (Percentage)

Fraction: 0.985 = $\frac{985}{1000}$

Percentage: $\frac{985}{1000}$ × 100% = 98.5%

4. (Percentage)

Fraction: $\frac{4}{5}$

Percentage: $\frac{4}{5}$ × 100% = 80%

5. (Decimal)

Fraction: 15% = $\frac{15}{100}$

Decimal: 15 ÷ 100 = 0.15

5. (Fraction)

Fraction: $\frac{15}{100}$

Simplest form: $\frac{15}{100}$ = $\frac{3}{20}$ (Divide both numerators and denominators by 5)
