Question

Give a button and a bookmark

Answer 1

Answer:

15 packages of buttons

9 packages of bookmarks

Step-by-step explanation:

We need to find the least common multiple (LCM) of 30 and 50.

30 = 2×3×5

50 = 2×5²

LCM = 2×3×5²

LCM = 150

Now we need to find a multiple of LCM that is greater than 400.

3LCM = 450

The committee needs at least 450 of each, which means they need at least 15 packages of buttons and 9 packages of bookmarks.

Answer 2

Let's note the information.

This is what we know:

Every buttons came in packages of 30 per student.

Every bookmark came in packages of 50 per person.

Know, we need to do some multiplying.

30 x 400 & 50 x 400

Now solve.

30 X 400 = 12000.

So we now know that they have an estimated 12000 buttons total.

Now, we find x for bookmarks.

50 x 400 = 20000

That means total that estimated that 20000 bookmarks will be given.
