Im good and all at math but I have a question this isn't tricky its like a math brain buster!Suppose you round each group of numbers to the nearest ten.which group of numbers all roundto the same number?

A.423,418,426
B.376,378,384
C.255,253,251
D.688,692,696

38

38
38

380

B is the saner because 376 rounds to 380, 378 rounds to 380, and 384 rounds to 380.

To determine which group of numbers will all round to the same number when rounded to the nearest ten, you'll need to round each number in the group and compare the results.

For group A:
- Rounding 423 to the nearest ten gives us 420.
- Rounding 418 to the nearest ten also gives us 420.
- Rounding 426 to the nearest ten gives us 430.

So in group A, only 423 and 418 round to the same number.

For group B:
- Rounding 376 to the nearest ten gives us 380.
- Rounding 378 to the nearest ten also gives us 380.
- Rounding 384 to the nearest ten also gives us 380.

In group B, all three numbers round to the same number.

For group C:
- Rounding 255 to the nearest ten gives us 260.
- Rounding 253 to the nearest ten gives us 250.
- Rounding 251 to the nearest ten also gives us 250.

In group C, 253 and 251 round to the same number.

For group D:
- Rounding 688 to the nearest ten gives us 690.
- Rounding 692 to the nearest ten also gives us 690.
- Rounding 696 to the nearest ten also gives us 700.

In group D, only 688 and 692 round to the same number.

Therefore, the group of numbers that all round to the same number when rounded to the nearest ten is B. 376, 378, 384.
