Answer 1

Amount of dry ice used =
`(1)/(4)\ pounds`

Explanation:

Weight of dry ice bought =
`(3)/(4)` pounds

Fraction of dry ice used =
`(1)/(3)`

To find the amount of dry ice used.

Solution:

Amount of dry ice used can be calculated as:

⇒
`(1)/(3)\textrm{of the total weight of dry ice bought}`

⇒
`(1)/(3)\ of\ (3)/(4)` pounds

⇒
`(1)/(3)* (3)/(4)` pounds

Multiplying numerator and denominators.

⇒
`(1* 3)/(3* 4)` pounds

⇒
`(3)/(12)` pounds

Simplifying fractions by dividing the numerator and denominator bt their GCF.

⇒
`(3/ 3)/(12/ 3)` pounds

⇒
`(1)/(4)` pounds

∴ Amount of dry ice used =
`(1)/(4)\ pounds`
