    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
