Answer the following and round to the correct number of significant figures (don't forget units).

a) 0.02123 m + 1.12 m + 0.00123 m =

b) 2.3 cm - 1.23 cm + 120 cm =

c) 25,430 km - 3,500 km + 200 km =

d) (1.21 x 10⁵ ) x (2.6 x 10³ ) =

e) 7.13 mm x 9.1 mm =

f) 3.0 cm x 8.222 cm =

g) 4.1 g ÷ 0.121 cm =

h) 0.413 ÷ (9.212 x 10³ ) =

i) (12.1 cm - 4.15 cm) / 35.64 g =

j) (11.00 m - 3.356 m) x 45.1 kg /35.64 s =

k) 73.0 x 1.340 x (25.31 – 1.6) =

l) (418.7 x 31.8) / (19.27 – 18.98) =
