4 carrots are needed to prepare a quarter liter of juice. How many carrots do you need to get half a liter of juice, a liter of juice, 2 liters of juice, 3 liters of juice

Part 1) How many carrots do you need to get half a liter of juice?

we know that

4 carrots are needed to prepare 1/4 liter of juice

using proportion

Find out how many carrots do you need to get 1/2 liter of juice

$\frac{4}{(1/4)}=\frac{x}{(1/2)}\\\\x=4(1/2)/(1/4)\\\\x=8\ carrots$

Part 2) How many carrots do you need to get a liter of juice?

we know that

4 carrots are needed to prepare 1/4 liter of juice

using proportion

Find out how many carrots do you need to get 1 liter of juice

$\frac{4}{(1/4)}=\frac{x}{1}\\\\x=4(1)/(1/4)\\\\x=16\ carrots$

Part 3) How many carrots do you need to get 2 liters of juice?

we know that

4 carrots are needed to prepare 1/4 liter of juice

using proportion

Find out how many carrots do you need to get 2 liters of juice

$\frac{4}{(1/4)}=\frac{x}{2}\\\\x=4(2)/(1/4)\\\\x=32\ carrots$

Part 4) How many carrots do you need to get 3 liters of juice?

we know that

4 carrots are needed to prepare 1/4 liter of juice

using proportion

Find out how many carrots do you need to get 3 liters of juice

$\frac{4}{(1/4)}=\frac{x}{3}\\\\x=4(3)/(1/4)\\\\x=48\ carrots$
