Enter the answer to the problem below, using the correct number or significan figures 100*3.25

100 * 3.25 = 325

In multiplying numbers with decimal points, you have to do the following.

1) remove the decimals and consider the number as a whole number
   from 3.25 to 325.
2) Consider the 100 in the equation. We know that whatever number is multiplied by 0 is always 0. So, we only consider 1.

   3  2  5
           1  0  0

  3  2  5  0  0

In big numbers we always start multiplying the number from the right side, which is 5. Since, the multiplicand is 1. Whatever number multiplied by 1 is always equal to that number.

325 * 1 = 325; add the two 0s attached to 1. = From 325 to 32500.

Now, 32500 is the product when we multiply 325 by 100. But, remember 325 is not really a whole number, it has decimals.

3.25 == count the number of places after the decimal. in this case, there are two places.

In the product 32500 == count the number of places from the last digit to know the placement of the decimals. There must be 2 places after the decimal.

FROM 32500 TO 325.00 = Since we can disregard the 00 after the decimal numbers.

100 * 3.25 = 325
