Answer:

4 packs of party plates and one pack of straws.

Explanation:

We have been given that there are 30 plates in a pack and 120 straws in a pack she needs exactly the same number of plates as straws.

To solve our given problem, we will convert find least common multiple of 30 and 120.

Multiples of 30: 30, 60, 90, 120,150,

Multiples of 120: 120, 240,...

We can see that least common multiple of 30 and 120 is 120.

$\text{Packs of party plates}=(120)/(30)=4$

$\text{Packs of party straws}=(120)/(120)=1$

Therefore, Helen should buy 4 packs of party plates and one pack of straws.
