How do you find the product of decimals?

How do you find the product of decimals?

Summary: When multiplying decimals, we use the following procedure:

1. Estimate the product.
2. Multiply to find the product. Multiply the decimals as if they were whole numbers. Ignore the decimal point.
3. Compare your estimate with your product to verify that your answer makes sense.

How do you multiply decimals without whole numbers?

How to Multiply Decimals

1. Multiply normally, ignoring the decimal points.
2. Then put the decimal point in the answer – it will have as many decimal places as the two original numbers combined.

What number can we multiply a decimal by to move the decimal to the right?

If you multiply a decimal by 10, the decimal point will move one place to the right. If you divide a decimal by 10, the decimal point will move one place to the left. If you multiply or divide by any power of 10, it will move a number of spaces equal to the number of 0’s.

When multiplying decimals Why is the product smaller?

Multiplying decimals by decimals When multiplying a number by a decimal less than one, the product will be smaller than the number being multiplied. This is because we are finding a fractional amount of a quantity. For example, 0.1 x 0.8 = 0.08, because the question is asking us to find one tenth of eight tenths.

How do you move 3 decimal places?

Example

1. Round this number to 3 decimal places.
2. Count along the first 3 numbers to the right of the decimal point.
3. Count along the first 3 numbers to the right of the decimal point.
4. Count along the first 3 numbers to the right of the decimal point.
5. Look at the next number (the 4th number after the decimal place)

When you multiply a positive decimal less than 1 by a decimal greater than 1 will the result always be greater than 1?

Whenever you multiply a positive number by a factor greater than 1, the product will be larger than the original number. Both of Ellen’s choices illustrate this principle. Whenever you multiply a positive number by a positive factor less than 1, the product will be smaller than the original number.
