Answer: 545,846,230
Step-by-step explanation: To round 545,846,229 to the nearest ten, we first find the digit in the rounding place which in this case is 2 in the tens place.
Next, look at the digit to the right of the rounding place which in this case is 9. The rules of rounding tell us that if the digit to the right of the rounding place is less than 5, we round down but if the digit to the right of the rounding place is greater than or equal to 5, we round up.
In this problem, since 9 is greater than or equal to 5, we round up. This means we add 1 to the digit in the rounding place so 2 becomes 3 and we change all digits to the right of the rounding place to 0.
Therefore, 545,846,229 rounded to the nearest 10 is 545,846,230.

Answer: The three odd integers are 11, 13 and 15.
Step-by-step explanation: The first point to note is that the three unknown numbers are consecutive, which means they follow one after the other. Also we are told that the numbers are consecutive “odd integers.” This also means there is a two-digit interval between one number and the next. Hence, if the first number is A, the next number will be A + 2, and the third number will be A + 2 + 2 (that is, A + 4)
At this point we can now derive the following expressions based on the information we have been given, which is;
The sum of the first and third (A + {A + 4} )equals the sum of the second and 13 ({A + 2} + 13). Therefore we can write this out as follows;
A + {A + 4} = {A + 2} + 13
After removing brackets we now have
A + A + 4 = A + 2 + 13
2A + 4 = A + 15
By collecting like terms we now have
2A - A = 15 - 4
(Remember that when a positive value crosses to the other side of the equation it becomes negative, and vice versa)
2A - A = 15 - 4
A = 11
Hence, the three consecutive integers are 11, 13 and 15.
