Question

What like break down on answer of question Bobby start in the juice that it takes for 15 minutes to prepare 3 1/4 cups of juice how many hours would it take how to prepare 32 1/2 cups of juice

Answer 1

Bobby takes 15 mins to prepare 3 1/4 cups of juice.

Lets find out how long does he takes to prepare 1 cup of juice.


`3 (1)/(4) \text { cups = } 15 \text { mins}`

Divide by 3 1/4 on both sides:

`\text { 1 cups = } 15 / 3 (1)/(4) \text { mins}`

Change to improper fraction:

`\text { 1 cups = } 15 / (13)/(4) \text { mins}`

Change the divide fraction to multiplication fraction:

`\text { 1 cups = } 15 * (4)/(13) \text { mins}`

Combine into single fraction:

`\text { 1 cups = } (60)/(13) \text { mins}`

Find time needed to prepare 32 1/2 cups of juice

`\text { 1 cups = } (60)/(13) \text { mins}`


`32 (1)/(2) \text { cups = } (60)/(13) * 32 (1)/(2) \text { mins}`


`32 (1)/(2) \text { cups = } (60)/(13) * (65)/(2) \text { mins}`


`32 (1)/(2) \text { cups = } 150 \text { mins}`

Convert mins to hours

`\text {Number of hours = } 150 / 60`


`\text {Number of hours = } 2 (1)/(2)`


`\bf \text {Answer: Bobby needs } 2 (1)/(2) \text { hours to make } 32 (1)/(2) \text { cups of juice. }`
