add 5 zeros.
1*10000
put a 1 in front and throw 5 zeros on the end.
as a general rule any number that ends in zeros, you cann multiply the non zero numbers and add the total number of zeros on the end.
30*20
multiply 3 and 2, get 6 then take the two zeros (one from 30 and one from 20)
get 600
Apart from using a calculator, specifically if you multiply a whole number by a power of 10:* To multiply a whole number by 10, add a zero to the whole number. * To multiply a whole number by 100, add two zeros to the whole number. * Etc.
10% = .10 (decimal equivilant) 10% can not be changed into a whole number unless you multiply by 10 or greater.
No, you cannot multiply 3 by any whole number to get 10. The closest whole numbers you can multiply by 3 to get a result near 10 are 3 (which gives 9) and 4 (which gives 12). However, neither of these products equals 10.
0.5 X 10 = 5
Take the number you have out of the whole, then dived it by the whole number. Multiply the resulting number by 100 and that's your percent.Example:What percentage is 7 of 10?7 / 10= .7.7 x 100 = 707 is 70% of 10.
To multiply a whole number by 10, just add a zero...
The simplest way is to multiply it by 10. 4.2 * 10 = 42. There are an endless number of ways to do it however.
There are 20 halves in 10. This is because each whole number can be divided into two halves, so when you multiply 10 by 2 (the number of halves in one whole), you get 20.
It is always zero !
10 x 26 = 260 To multiply an integer (whole number) by 10, simply add a zero to the end of the number.
When you multiply by 10, you add one more zero. 10^10 x 10^1 = 10^11
its always the same
