Show the work for $300.00 x $11.50?

Question

My daughter is in 7th grade and we would like to know if you drop a 0? When we did the work we have an extra 0

Answer 1

$1150 x 3 = $3450.00.

Answer 2

Well, there's not really much use for the unit $². Anyway, it depends on if you want to keep the decimals. If you do 300 * 11.5, then you don't need to drop anything. If you keep the numbers as it and you use 300.00 * 11.50, you should end up with four decimal places, and since money only needs two, you drop the last two.

Answer 3

You can do it this way:

   1 1 . 5

x         3 0 0

-------------------

   3 4   5 0 0

Since it has one decimal point, the answer above would be 3450.0 which we can leave out.

Answer 4

The number of decimal digits in the product is the 4, because you have 2 from 300.00 and another 2 from 11.50. The product is 3450.0000, and you can then drop any trailing zeroes to the right of the decimal point.

By the way, multiplying two dollar amounts doesn't make sense.

Answer 5

________ <you don't need to multiply the last 0 since 0x# = 0

1500.00

Answer 6

     300

_______

    1500

    3000

+ 30000

_______

34500

Because it is a decimal point bring your one decimal place over, giving you

3450.0

Each time you go down a line you add an extra zero, for example.

first line no extra zeros, second line 1, third line 2, etc

Answer 8

ok, here's the work step by step.

1) multiply the first zero from the $11.50 to every digit in $300.00. so it'd look like this:

$300.00

x $11.50

_______

   00000

2) Add a zero on the right hand most side before you start multiplying.  multiply the 5 from $11.50 to every digit in $300.00. This is what everything will look like so far:

$300.00

x $11.50

________

   00000

1500000

3) Add 2 zeros from the right hand most side before you start multiplying. multiply the 1 from $11.50 to every digit in $300.00, so it'd look like this so far:

$300.00

x$11.50

________

   00000

1500000

3000000

4) Add 3 zeros from the right hand most side before you start multiplying. Multiply the final 1 from $11.50 to every digit from $300.00. so it'd look like this:

$300.00

x$11.50

________

   00000

1500000

3000000

30000000

4) Add the numbers up. When you do that you get a grand total of 34,500,000

5) time to tack on the decimal. When you look at at $300 and $11.50, you see that there's 2 numbers after the decimal points. Altogether, there are 4 numbers after the decimal place, so you move 4 places to the left from the right hand most side, and place the decimal place there. So the final answer would be: $3,450.00

Answer 9

Yes you can drop a 0. Therefore, u get 300 x 11,5 = 3450. Good day!
