You what to understand that 0.1 = 1/10 so you really have.. 100* 1/10 = 100/10 which clearly equals 10 You must not understand the "rules of decimals" yet. Look things over more carefully. For me the rules of decimals says that when you have multiplication, if you move one decimal to the right you must move another decimal to the left by the same amount In your example.. 100 x 0.1 =10 It works because 100 = 100.0 Note when you move a decimal to the right you are effectively multiplying the number by 10, for example... 23.3 x 10 = 233.0 When you move it to the left you are dividing it by 10.... 23.3 /10 = 23.3 ÷ 10 =2.33
sqrt(100) = ±10 Multiplying this by 4 gives either 10 x 4 = 40 or -10 x 4 = -40.

Yes.For example 10% of 20 = 10/100 * 20 = 2AND 20% of 10 = 20/100 * 10 = 2.In both cases we are effectively multiplying a & b and then dividing by 100 so the result will always be the same.

6/10 can be converted into percentage by multiplying it by 100 to get 60 percent: 6/10 = 6/10 x 100% = 60%
Any number being squared should be it be multiplying 100. So 10 × 100 = 1000.
500 * 0.2 which is 100 actually if you are multiplying 500x0.2 it would = 10 not 100.
To find this number we divide 10 by (1/10). This is equivalent to multiplying by the reciprocal of 1/10 which is 10. So, 10 / (1/10) = 10 * 10 = 100. Thus there are 100 tenths in 10.

$3.20 is 32% of $10. This is found simply by dividing 10 by 3.2 and multiplying that by 100 to get the percent value.

Moving the decimal point one place to the right is the same as multiplying both, he numerator and the denominator by 10. That is, you are effectively multiplying by 10/10 which equals 1. And since multiplication by 1 does not change the result, it is OK to do that. Similarly, moving two palces to the right is multiplying by 100/100. Similarly moving left.
