Question

Samuel needs 332 feet of wood to build a fence. The wood comes in lengths of 15 feet.

How many total pieces of wood will Samuel need? Theresa needs twice as many feet of wood as Samuel. How many pieces of wood does Theresa need?

Answer 1

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 2

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.
