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 of two rational numbers is always a rational number.
No, the product of two negative numbers is always a positive.
Multiply the numbers, count the total number of decimal places in the problem and place that many in your product.
Zeroes to the left of the decimal point are significant if there is a decimal point present. Zeroes between numbers are always significant. Zeroes to the right of the decimal point are always significant. Non-zero numbers except for the last are always significant. The last non-zero number is always insignificant.
Any number, negative or positive, can be expressed as a decimal number. So a negative number can always be expressed as a negative decimal.

A rational number in essence is any number that can be expressed as a fraction of integers (i.e. repeating decimal). Taking the product of any number of rational numbers will always yield another rational number.
The product of negative number and a positive number is always a negative. The product of two positive numbers, or two negative numbers, is always a positive.

The product of two rational numbers is always a rational number.
No, the product of two negative numbers is always a positive.
The product of two odd numbers is always an odd number.
No, the product will always be even.
The product of two prime numbers is always a composite number, and it never is a prime number.
The product of all those numbers will always be a negative number.
Multiply the numbers, count the total number of decimal places in the problem and place that many in your product.
