Yes, it is true for all whole numbers (integers). It is not true for non integers.
It is better to think of multiplying by 10 as moving the decimal point 1 place to the right.
So, 3 * 10 = 30 (We can think of 3 as actually being 3.0, so by moving our decimal point one place to the right we get 30).
Likewise 3.5 * 10 = 35 (Here the rule of adding a 0 does not work as 3.5 isn't a whole number, but moving the decimal point one place to the right always works).

ShayLea said that if you multiply the numerator and denominator of a fraction by the same number ou get an equivalent fraction Is this true Why or why not?
This is true; if you multiply both numbers by the same number, the proportion will remain the same.
When you multiply a decimal by a whole number the number places in the product is the same as the number of decimal places in the decimal factor true or false?
True
When you multiply a whole number by 10 what is always true about the ones place?
It is always zero !
What is true about two odd numbers?

When you multiply a decimal by a whole number the number places in the product is the same as the number of decimal places in the decimal factor true or false?
True
Is it true that To convert from liters to milliliters multiply the number of liters by 10.?
No, that's not true. Since "milli-" means 1/1000, you need to multiply by 1000, not by 10.
When you multiply a whole number by 10 what is always true about the ones place?
It is always zero !
Is it true that if you multiply an even number by anything the product will be an even number?
Yes, an even number multiplied by an odd number or an even number will give you an even number.
When you multiply a whole number by 10 what is always true about the ones place in the product?
its always the same
What is multiplying factor in energy measurement?
It is a number, usually multiple of 10, that we have to multiply the reading of the measurement with, in order to have the true number. So if the reading is 1,23456 and the multiplying factor is 100, then the true number is 123,456.
What is the validity of 0 in the number system if 1011.099009900990099009900990099099111 is true?
1011.09900990.... is a number. It is neither true or false - just a number.
What is true about two odd numbers?
When you add them, you always get an even number; when you multiply them, the result is always odd.
Is it true that when you multiply a number by another number less than 1 you get a product greater than the first number?
No, this statement is not true. When you multiply a number by another number less than 1, the product will be smaller than the first number. For example, multiplying 5 by 0.5 gives a product of 2.5, which is smaller than 5.
When you multiply a decimal by a whole number is the number of decimal places in the product the same as the number of decimal places in the decimal factor?
This is not necessarily true. 2 x 0.55 = 1.1
