The answer will depend on the degree to which the number is rounded. Without any indication of that, it is not possible to answer the question sensibly.
2.5 rounded to the nearest two is 2.
It is 6.7 when rounded to 2 significant figures
It is 2 when rounded to the nearest whole number.
1,430 rounded to 2 significant figures is 1,400
009999991 rounded to 2 significant digits is 1.0e7
2.2 rounded is 2
2.5 rounded to the nearest two is 2.
1686 rounded to 2 significant figures is 1700
2 + 2If you used round numbers as 1.6 rounded up is 2 as well as 2.4 rounded is 2 so if you do 2.4 + 2.4 this equals 4.8 which can be rounded to 5. which in rounded terms is 2+2=5 but originally it is 2.4+2.4=4.8
It is 6.7 when rounded to 2 significant figures
It is 2 when rounded to the nearest whole number.
215,000,000 rounded to 2 decimal points is 215,000,000.00
1,430 rounded to 2 significant figures is 1,400
009999991 rounded to 2 significant digits is 1.0e7
2711 rounded to 2 significant digits is 2700
2.412 rounded to the nearest tenth is 2.4. Rounded to the nearest whole number would be 2.
0.625 rounded of to 2 decimal places = 0.63
