3. Add these measurements

a) 16.5 cm + 8 cm + 4.37 cm =

13.25 g + 10.00 g + 9.6 g =

c) 2.36 m + 3.38 m + 0.355 m + 1.06m =

d) 0.0853 g + 0.0547 g + 0.037g + 0.00387 g =

28.87 or 29 cm

32.85 or 32.9 g

0.18087 or 0.181 g


Entry task october 1 st monday

4. Subtract these measurements

23.27 km - 12.058 km =

13.57 g - 6.3 g =

c) 350.0 m - 200 m =

d) 27.68 cm - 14.369 cm =

Entry task october 1 st monday

Why are significant figures so important in scientific data?

Using two different instruments, I measured the length of my foot. Ruler #1 measured it to be 22.00 centimeters and ruler #2 had a measurement of 22 centimeters. Explain the difference between the two measurements.

The more numbers in your measurement the more precise the measuring tool.

Ruler 1 has 4 significant figures in its measurement verse Ruler 2 which has 2. Ruler 1 is more precise than Ruler 2.
