Add a 0 onto 100, or add 2 0's onto 10.
Multiply by 10 = add a 0
Multiply by 100= add 00
Multiply by 1000 = add 00
Teachers prefere not to say 'add a 0'. This is like a cheat, and does not work for decimals.

There are 100 ones in 10 tens. This is because each ten consists of 10 ones, so multiplying 10 by 10 gives you 100.
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.

6/10 can be converted into percentage by multiplying it by 100 to get 60 percent: 6/10 = 6/10 x 100% = 60%
There are 100 ones in 10 tens. This is because each ten consists of 10 ones, so multiplying 10 by 10 gives you 100.
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.

Multiplying fractions is all about division
$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.
