What will be the value of 1 x 0.3 x 0.01 x 0.003?

1 × 0.3 × 0.01 × 0.003 = 0.0009

Explanation

To find the value of 1×0.3×0.01×0.003, you simply multiply all the numbers together:

Start with the first number, which is 1.

Multiply 1 by the second number, which is 0.3. This gives you 0.3.

Multiply the result (0.3) by the third number, which is 0.01. This gives you 0.003.

Finally, multiply the result (0.003) by the fourth number, which is 0.003. This gives you 0.0009.

So, when you multiply 1 by 0.3, then by 0.01, and then by 0.003, you get the result 0.0009.

1×0.3×0.01×0.003=0.0009

So, the value is 0.0009.

Multiplication of Decimal Numbers

Multiplying decimals might seem tricky at first, but it's quite simple once you break it down! Here's the process:

Step 1: Ignore the decimals for now. Treat both numbers as whole numbers and multiply them like you normally would. Forget about the decimal points for the moment.

Step 2: Count the total number of decimal places in both original numbers. Add the number of digits behind the decimal point in each number. This tells you how many digits to the right of the decimal point your answer should have.

Step 3: Place the decimal point in your answer. Starting from the rightmost digit, count the same number of digits as you found in step 2 and insert the decimal point there.

Examples:

Example 1: Multiply 2.34 by 5.1

  1. Ignore the decimals: 234 * 51 = 11994
  2. Count decimal places: 2 + 1 = 3 decimal places
  3. Place the decimal: 11.994

Example 2: Multiply 0.075 by 0.8

  1. Ignore the decimals: 75 * 8 = 600
  2. Count decimal places: 2 + 1 = 3 decimal places
  3. Place the decimal: 0.060

Tips:

  • If a number has no decimal, consider it as having zero decimal places (e.g., 5 is the same as 5.0).
  • You can use a grid or place value table to help organize your multiplication and keep track of decimal places.
  • There are online calculators and educational websites that can provide you with interactive practice and guided tutorials.
