Answer 1

1. 9
`(1)/(11)`%

2. 0.45

3. 98.5%

4. 80%

5. Decimal: 0.15, Fraction:
`(3)/(20)`

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:
`(1)/(11)`

Percentage:
`(1)/(11)` × 100% = 9
`(1)/(11)`%

2. (Decimal)

Fraction:
`(45)/(100)`

Decimal: 45 ÷ 100 = 0.45

3. (Percentage)

Fraction: 0.985 =
`(985)/(1000)`

Percentage:
`(985)/(1000)` × 100% = 98.5%

4. (Percentage)

Fraction:
`(4)/(5)`

Percentage:
`(4)/(5)` × 100% = 80%

5. (Decimal)

Fraction: 15% =
`(15)/(100)`

Decimal: 15 ÷ 100 = 0.15

5. (Fraction)

Fraction:
`(15)/(100)`

Simplest form:
`(15)/(100)` =
`(3)/(20)` (Divide both numerators and denominators by 5)
