Question

outcome 2

  1. write the prefix order for converting in the metric system (remember \king henry died...\)

____ __ __ __ __ __ ____

  1. one milligram is how many centigrams? _____________
  2. how many meters are in one kilometer? _____________
  3. how many kilometers are in one meter? _____________
  4. 2.55l = cl _____________
  5. 0.4682 mm = dm _____________
  6. 100.99 m = hm _____________
  7. 0.002 ml = dkl _____________

for questions 13-16, compare the two values using <, >, or = (hint: pick one measurement to change into the unit of other and then compare the two once they are the same unit)

  1. 1.0 mm ____ 10 cm 14) 25 cm ____ 1 m

for questions 17-20, compare the two values using <, >, or = (hint: pick one measurement to change into the unit of other and then compare the two once they are the same unit)

  1. r or l: ml to l 18) r or l: g to cg
  2. how many minutes in a quarter of an hour?
  3. a half - hour is how many minutes? how many seconds in this same time?

Explanation:

1) Metric prefix order

From largest to smallest: Kilo (K), Hecto (H), Deka (Da), base Unit, Deci (D), Centi (C), Milli (M).

2) mg to cg conversion

1 mg = 0.01 cg (since 1 cg = 10 mg).

3) km to m conversion

1 km = 1000 m.

4) m to km conversion

1 m = 0.001 km.

5) L to cL conversion

1 L = 100 cL → 2.55 L × 100 = 255 cL.

6) mm to dm conversion

1 mm = 0.01 dm → 0.4682 mm × 0.01 = 0.004682 dm.

7) m to hm conversion

1 m = 0.01 hm → 100.99 m × 0.01 = 1.0099 hm.

8) mL to dkL conversion

1 mL = 1×10⁻⁷ dkL → 0.002 mL × 1×10⁻⁷ = 2×10⁻⁸ dkL.

13) 1.0 mm vs 10 cm

10 cm = 100 mm → 1.0 mm < 100 mm.

14) 25 cm vs 1 m

1 m = 100 cm → 25 cm < 100 cm.

17) mL to L direction

mL is smaller than L; convert by moving decimal left.

18) g to cg direction

g is larger than cg; convert by moving decimal right.

21) Quarter hour to minutes

1 hour = 60 min → 60 × 0.25 = 15 min.

22) Half hour to min/sec

Half hour = 30 min; 30 min × 60 = 1800 sec.

Answer:

  1. Kilo, Hecto, Deka, Unit, Deci, Centi, Milli
  2. 0.01
  3. 1000
  4. 0.001
  5. 255
  6. 0.004682
  7. 1.0099
  8. 2×10⁻⁸
  9. <
  10. <
  11. L
  12. R
  13. 15
  14. 30; 1800
