5.1647 to three decimal places is 5.165. When rounding figures to decimal places, you look at the next digit. In this example - IF the fourth digit had been 4 or less, you would round DOWN to 5.164. HOWEVER, since the fourth digit is 5 or more (in this case 7), you round UP to give 5.165.

phi = 1.618 to 3 dp pi = 3.142 to 3 dp
7. 3.012 has 3 dp 6.2034 has 4 dp so their product has 3 + 4 = 7 dp. If there are trailing zeros, these would not normally be written and so would reduce the number of dp; the last digit is 2 x 4 = 8, which is not zero, so there will be 7 dp in their product.
Rounded off to how many decimal places (dp) !... 0.795 (3 dp) 0.80 (2dp)
The answer is 9.577 (to 3 dp).
Infinitely many. 1 + 1328 2 + 1327 and so on. Then consider numbers to 1 decimal place (dp). 1.1 + 1327.9 1.2 + 1327.8 etc. Next you can include numbers to 2 dp, 3 dp, 4 dp all the way to infinitely many dp. Next you can look at sums of 3 number, 4 number, ... infinitely many numbers.
