True
There will be five decimal places.

When multiplying, you move the decimal to the right. The number of places you move the decimal to the right is equal to the total number of decimal places in the numbers being multiplied. For example, if you are multiplying 2.5 by 3.2, you would move the decimal a total of three places to the right to get the final product.
When multiplying by 100, move the decimal point two places to the right. So in this case: 0.049 x 100 = 4.9
Yes. You first multiply, then however many decimal places you were multiplying, you move over.
There will be five decimal places.

three
The product of 0.3 and 3 is 0.9. To calculate this, you simply multiply 0.3 by 3. When multiplying a decimal by a whole number, you can ignore the decimal point temporarily and multiply the numbers as if they were whole numbers. The final product will have the same number of decimal places as the total number of decimal places in the numbers being multiplied.
Since both multiplicands are integers, then so is their product.

To find the number of decimal places in a product of decimal numbers, add up the total number of decimal places in each of the factors. For example, if you have 2.5 multiplied by 4.75, there are two decimal places in 2.5 and two decimal places in 4.75, so the product will have a total of four decimal places.
The product will have at most 2 decimal places.
Product means numbers multiplied together. Multiplying by 10, 100, 1000 etc is easy, you just move the decimal point one place to the right for every zero. To find this product, move the decimal to the right 2 places in 3.8 and we have 380
When multiplying a whole number by a decimal with two places, ignore the decimal point and multiply as if you were multiplying two whole numbers. After you get the answer, re-insert the decimal point so that the product has two decimal places.
Two places.
Not necessarily: for example, consider 0.5 * 4 = 2
