how do multiply decimals by whole numbers?

Do the multiplication as if the decimal point wasn't there.  In this case, the problem becomes 69 times 38, and your answer would be 2622.\n\nThen, when you're done, count the number of decimal places after the point, in both of the numbers you're multiplying.  In this case, it would be one - the 8 in 3.8.\n\nThen count that same number of spaces from the end in your answer, and add the decimal point in that spot.  That would change your answer to 262.2.\n\nHere's another example:\n9.7 times 4.3\nChange it to 97 times 43\nThe result is 4171\nCount the numbers after the decimals - this time it's two - the 7 in 9.7, and the 3 in 4.3\nCounting back two from the end of 4171 gets us an answer of 41.71

you can use the isNaN function. If the given text is whole number, then Math.round(n)=n right? So, here is the function\n\nfunction get_type(txt){\nvar type;\nif(!isNaN(txt)){\nvar rnd = Math.round(txt);\nif(rnd==txt){\ntype="wholenumber";\n}\nelse\n{\ntype="decimal";\n}\n}\nelse\n{\ntype="char";\n}\nreturn type\n}\n\nThis function returns "wholenumber" if whole number, "decimal" if decimal, or "char" if character.\n\nHOPE That helps

It's just like the decimal system, only based on the number 2 instead of the number 10..........\n\n1  10  100  1000  10000  100000  1000000  etc... - Decimal\n\n1  2  4  8  16  32  64  128  256  512  1024  etc.. - Binary

U have to use JavaScript for calculations.\nThere is a function 'eval' in JavaScript that takes the operators and operands as input and returns the result.\n\nE.g:  eval(7*5), it will return 35.

Multiply that by about 0.458

0.01 is already decimal..\nif you want 0.01%, it should be 0.01/100=0.0001

Divide the top by the bottom.  Put the decimal over 1.

To divide decimal numbers:\n\n1.If the divisor is not a whole number:\n      *Move the decimal point in the divisor all the way to the right (to make it a whole number).\n      *Move the decimal point in the dividend the same number of places.\n\n   2.Divide as usual. If the divisor doesn't go into the dividend evenly, add zeroes to the right of the last digit in the dividend and keep dividing until it comes out evenly or a repeating pattern shows up.\n\n   3. Position the decimal point in the result directly above the decimal point in the dividend. \n\n   4. Check your answer: Use the calculator and multiply the quotient by the divisor.

You multiply the decimals by 12 and the whole number will represent the amount on inches. If there are decimals left from the past result, then multiply these decimals by 8 if you are using the units that divide the inch in 8 parts or multiply them by 16 if you are using the units that divide the inch in 16 parts.

although there can be some patterns seen in the numbers it is not a repeating decimal and can be taken out to a lot more decimal places then humans can calculate.  Also if you put it into fraction (22/7) that is the most accurate way to actually utilize the number.

To convert a fraction to decimal using a calculator, its just the top number (numberator) divided by the bottom number (denominator).\n\n1 ÷ 4 = 0.25\n\nTo convert it without a calculator, you can use equilavent fractions, which works for some easy denominators. Just change the denominator to a power of 10 (10,100,1000,...) by multiplying the top and bottom by the same amount, which keeps the same value of the fraction.\n\n1/4 = 1*25 / 4*25 = 25/100 = 25 hundredths\n\n25 hundredths ends in the hundredths column, so 0.25\n(thats the same as 2 tenths and 5 hundredths)\n\nYou can also work out any fraction into a decimal using long division, just proceed past the decimal as normal, putting in extra 0's\n\n1 ÷ 4 = 4 into 1 = 4 into 1.00\n\n4 ) 1.00\n\n4 into 1 goes 0 remainder 1\n4 into 10 goes 2 remainder 2\n4 into 20 goes 5\n\n0.25, keeping the decimal point in the same place\n\nThis always works, although you will need to decide when to stop for a repeating decimal such as 1/3\n\n3 ) 1.0000...\n\n3 into 1 goes 0 remainder 1\n3 into 10 goes 3 remainder 1\n3 into 10 goes 3 remainder 1\n3 into 10 goes 3 remainder 1\n3 into 10 goes 3 remainder 1\n.\n.\n.\n\n1/3 = 0.33333...

1,500,000 as a decimal is: 1,500,000∙0\n\nIf 3,000,000 = 0∙03% then;\n 3,000,000 = 0∙03%     (÷ 3,000,000)\n 1 = 0∙000, 000, 01%    (x 1,500,000)\n 1,500,000 = 0∙015%

u should write it like\n7.52*10^-4

simply multiply it with 0.4
