To grow 24 plants, Julia needs 6 seed packets.


Have an AWESOME day! :)

Answer 2

To determine how many seed packets are needed to grow 24 plants, considering that the relationship between the number of packets and the plants grown are directly proportional, you can use cross multiplication:

20 plants → 5 seed packets

24 plants → x seed packets

Both relationships are at the same ratio so that:

`(5)/(20)=(x)/(24)`

Multiply both sides by 24 to determine the number of seed packets needed:

`\begin{gathered} 24\cdot(5)/(20)=24\cdot(x)/(24) \\ 6=x \end{gathered}`

To grow 24 plants, Julia needs 6 seed packets.
