Answer 2

`\large\boxed{\large\boxed{0.2deciliter}}`

Step-by-step explanation:

Build your conversion factors using the conversion table:

• 
  `1 cup = 0.237 liters\implies 1=0.237liters/1cup`

From the prefixes used in the metric system, you know that 1 deciliter = 0.100 liters. Then:

• 
  `1 deciliter = 0.100 liters\implies 1=1deciliter/0.100liters`

Arrange the expression to simplify the units and convert from cups to deciliters:

• 
  `9cups* 0.237liters/cup* 1deciliter/0.100liters=0.2133deciliter`

Round to the nearest tenth: 0.2 deciliter.
