Sagot :
as i've said from the previous post of question, a number can be rounded up when the number to its right is 5-9 and will be rounded down when it's 1-4 and remains the same when it is zero.
so here's the list of numbers that can be rounded to 530 when rounding it to the nearest tens
525 ----> 530
526 -----> 530
527 -----> 530
528 -----> 530
529 -----> 530
530 ---530
531 -----> 530
532 -----> 530
533 -----> 530
534 -----> 530
