It is 9.906
9 as a decimal can be written 9.03/10ths as a decimal can be written 0.317/100ths as a decimal can be writen 0.17If you add 9.0 to 0.3 and then add 0.17 the result is 9.47
7 plus 0.9 plus 0.03 can be written in decimal form as 7.93.
The number 5.9 is already in decimal form. We know that 5.9 is 5 plus 9/10. The 9/10 is 0.9, so 5 + 9/10 is 5.9 as already written in decimal form.
When multiplying one decimal by another decimal, the result will always have a larger number of digits to the right of the decimal point than either of the two factors. The number of digits to the right is the total of the digits for the two factors.Example:.25 x .3 = .075 (two digits plus one = three)You can make this clearer by putting all three in one of the numbers to start,making one of the factors a whole number..25 x .3 = .025 x 3 = .075Example:.02 x .03 = .0006 (the product is 6, the number of places is 4)In fraction form, this would be2/100 x 3/100 = 6/10000
.7
6.00 + 1.40 + 1.50 = -------- 8.90 The answer is 8.90 ( the number is a decimal).
Assuming you meant 85.4 + 0.97 + 1.30, the correct number of decimal places should be 1, that is, only one digit after the decimal point. When determining the number of significant digits for purposes of addition, you round it off to the least precise of the numbers - the one with the fewest digits to the right of the decimal point. If you are asking how many total digits the answer should have - the answer would be 3 - (the sum would be written 87.7).
The first number (01001101) is equal to the decimal number 77. The second number (00100010) is equal to the decimal number 34. If you add the two together in decimal, you get 111. Expressed as a binary number, 111 is equal to 01101111.
As a decimal fraction, it is 8.81 This can also be written as 881/100.
You simply delete the plus or minus sign.
A negative decimal plus a negative decimal equals a more negative decimal
Yes, as long as ' r ' is a whole number, and not a fraction or decimal.
