In the parts that follow select whether the number presented in statement a is greater than, less than, or equal to the number presented in statement b. be sure to follow all of the rules concerning significant figures. statement a: 2.567 km, to two significant figures. statement b: 2.567 km, to three significant figuresso, statement a is statement bstatement a: (2.567 km+ 3.146 km), to two significant figures. statement b: (2.567 km, to two significant figures) + (3.146 km, to two significant figures).so, statement a is b

a) Therefore 2.6km is greater than 2.57km.

Statement A is greater than statement B.

b) Therefore 5.7km is equal to 5.7km

Statement A is equal to statement B

Explanation:

a) Statement A : 2.567km to two significant figures.

2.567km 2. S.F = 2.6km

Statement B : 2.567km to three significant figures.

2.567km 3 S.F = 2.57km

Therefore 2.6km is greater than 2.57km.

Statement A is greater than statement B.

b) statement A: (2.567 km + 3.146km) to 2 S.F

(2.567km + 3.146km) = 5.713km to 2 S.F = 5.7km

Statement B : (2.567 km, to two significant figures) + (3.146 km, to two significant figures).

2.567km to 2 S.F = 2.6km

3.146km to 2 S.F = 3.1km

2.6km + 3.1km = 5.7km

Therefore 5.7km is equal to 5.7km

Statement A is equal to statement B
