0.37 meters of netting

<h3>Further explanation</h3>

<u>Given:</u>

Mrs. Nguyen used 1.48 meters of netting to make 4 identical mini hockey goals.

<u>Question:</u>

How much netting did she use per goal?

<u>The Process:</u>

We will solve the problem of conversion or in other words the ratio or proportion.

Option A: the conversion

Mrs. Nguyen used 1.48 meters of netting to make 4 identical mini hockey goals.

Then for every 1 goal, she needs 0.37 meters of netting.

Because $\boxed{ \ 1 \ goal \times \frac{1.48 \ meters}{4 \ goals} = 0.37 \ meters \ of \ netting.}$

Option B: the ratio (or proportion)

In the ratio, we process as follows:

$\boxed{ \ 4 \ goals : 1.48 \ meters \ of \ netting \ }$

Both are divided by 4.

$\boxed{ \ 1 \ goals : 0.37 \ meters \ of \ netting \ }$

Thus, she uses 0.37 meters of netting per goal.

Alternative problem

How much netting did she use for 8 goals?

$\boxed{ \ 8 \ goal \times \frac{1.48 \ meters}{4 \ goals} = \ ? \ }$ meters of netting.

We cross out eight and four because they can be divided.

$\boxed{ \ 2 \times 1.48 \ meters = 2.96 \ meters \ of \ netting. \ }$

She uses 2.96 meters of netting to make 8 identical mini hockey goals.

❗️‼️❗️HELP❗️‼️❗️ Harry had a pile of 48 pennies. He organized them into a rectangular array with exactly four rows with 12 penni

Viefleur [7K]

Answer:

One array you could make is 2 rows of pennies with 24 pennies in each row. Another array you could make is 3 rows of pennies with 16 pennies in each row.

Yet another array you could make is 6 rows of pennies with 8 pennies in each row.

You could also switch all of these arrays around. For example:

- 24 rows with 2 pennies in each row

- 12 rows with 4 pennies in each row

- 8 rows with 6 pennies in each row

- 16 rows with 3 pennies in each row
