When "n" is any other number in the tenths place holder such as .1, .2, .3, ...., .8, .9 and no other digits in any other place holder.

To find the answer all you do is add a zero to the number.

The product is 0.0036 Simple method is to multiply the two numbers. The decimal place is determined by the addition of the number of decimal places in each factor (2 places in 0.04, 2 places in 0.09), 2 +2 = 4.

Before comparing the two numbers, you must first find the product of 1.2 and 3.6. To multiply with decimals, first multiply the numbers as if they didn't have any.12 x 36 = 432Now, to place the decimal point correctly in the answer, count the number of places that are in the original multipliers (1.2 and 3.6). There are two: .2 and .6. So, place the decimal in the product two spaces from the right. Your answer now becomes 4.32, which is less than 5.

To find the answer, multiply 7 times the number in the ones place (3) to get 21. Place the 1 in the one's place in the answer and carry the 2 to the tens place. Multiply the 6 in the tens place by the 7 to get 42 and add the 2 that you carried to get 44. Place that in the answer. The answer is 441.
