Answer:

23 and 45

Explanation:

This is really just a simple division question. All we have to do to solve the first half is divide 332 by 15:


332 / 15 = 22.133333333

We'll want to round that up to 23, because it seems they're asking for integers here.

For the next part of the question, all we have to do is double the result of the last operation and round that number up as well:


22.13333333 *2 = 44.2666667

Which rounded gives us 45.

Hope this helps!

Answer:

Samuel will need 23 pieces of wood.

Theresa will need 46 pieces of wood.

Explanation:

To find how many total pieces Samuel will need, we have to divide 332 feet into 15, since each piece of wood is equivalent to 15 feet:


332 ÷
15=22.1333

Samuel can't have a portion of wood, the wood pieces he has must be represented as a whole number. We have to round up to 23 pieces of wood.

Samuel will need 23 pieces of wood to build his fence.

_

If Theresa needs twice as many feet as wood, we have to multiply Samuel's pieces of wood by its length (15 feet):


23 ×
15=345

Multiply
345 by 2:


345 ×
2=690

Now, divide
690 by
15:


690 ÷
15


=46

Theresa will need 46 pieces of wood.
