What are the rules for multiplying decimals?
Multiply the numbers without the decimal points.Count the total number of digits after the decimal point in the original numbers and put the decimal point into the answer so that there are the same number of digits after the decimal point.Examples:2.4 x 3.24do 24 x 324 = 7776 There is one digit in 2.4 and two in 3.24 after the decimal points making three digits in total, so insert the decimal point into the answer so that there are three digits after it: 7776 → 7.776⇒ 2.4 x 3.24 = 7.7762.5 x 3.26do 25 x 326 = 8150 There is one digit in 2.5 and two in 3.26 after the decimal points making three digits in total, so insert the decimal point into the answer so that there are three digits after it: 8150 → 8.150⇒ 2.5 x 3.26 = 8.152.5 x 0.02do 25 x 2 = 50 There is one digit in 2.5 and two in 0.02 after the decimal points making three digits in total, so insert the decimal point into the answer so that there are three digits after it: 50 → 0.050⇒ 2.5 x 0.02 = 0.05

How many strings of four decimal digit have exactly three digit that are nine?
The number of strings of four decimal digits that have exactly three digits which are nine is the number of ways to choose three places to choose the nines multiplied by the number of possibilities for the other digits (because you can put all of the possibilities in an array so that each column has a different way of arranging the nines and that each row has a different set of other digits (because they do not affect each other)). The number of ways to choose the three places to choose the nines is the same as the number of ways of choosing 4-3=1 spot for there not to be a nine. The number of ways of choosing 1 spot where there are 4 spots is 4 (the first, the second, the third, or the fourth). Since there are 9 digits that are not nine, the number of choices for the other digits is 9 (since there is only one digit). Thus, there are 4*9=36 strings of four decimal digits that have exactly three digits which are nine.
How many strings of three decimal digits Have exactly two digits that are 4?
Only three groups: 44x, 4x4, and x44, where 'x' is not 4. yet you have to multiply each group 9 times because x could be 1,2,3...9,0 but not 4 so answer: 9*3
