Describe a real life multiplication situation for which an estimate makes sense

Drupady [299]

If you are trying to create a garden of potted plants, you would find out how much soil each pot needs/holds and multiply that by how many pots you plan to use. then you would go to the store for potting soil, which let’s say came in smaller packs and you need to purchase multiple. use multiplication estimation to estimate how many bags you’d need.
I know this is a dumb example...sorry this is one I remember from my fourth grade math teacher ahah

9 days ago the area covered by a mold and a piece of bread with three square inches today the mold covers 9 square inches find t

Kazeer [188]

9 days ago, the mold covered an area of $3in^{2}$ .

Today (after 9 days), the mold covers an area of $9in^{2}$ .

What is the increase in area? It went from 3 to 9. So the increase is $9-3=6 in^{2}$ .

Now, we need to find rate of change. It means to find how much the area increased every day over the past 9 days. We simply divide the increase (6) by the total number of days (9) to find the rate per day. So we have,

$\frac{6}{9} =\frac{2}{3} in^{2}$
