Question

Round of 728 to (2sf.)

Answer 1

Answer:

730

Step-by-step explanation:

2 s.f. means 2 significant figures and the 2 s.f. in this number are 2 and 8 we need to find a number greater than 5 or simply 5 if we can't find it the number becomes 720 but in here we have 8 so when we round it off the number becomes 30 because we are rounding it off in 10's and not one's if we were rounding it off in one's the answer wold be 729 but we are rounding off in 10's so the answer is 730
