Question
outcome 2
- write the prefix order for converting in the metric system (remember \king henry died...\)
____ __ __ __ __ __ ____
- one milligram is how many centigrams? _____________
- how many meters are in one kilometer? _____________
- how many kilometers are in one meter? _____________
- 2.55l = cl _____________
- 0.4682 mm = dm _____________
- 100.99 m = hm _____________
- 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)
- 1.0 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)
- r or l: ml to l 18) r or l: g to cg
- how many minutes in a quarter of an hour?
- a half - hour is how many minutes? how many seconds in this same time?
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.
