so use conversion factors to cancel units
ex
12 in=1ft
to convert 2 ft to in yo have to do
2 ft times 1=same thing right so
12in/1ft=1 so
2ft/1 times 12in/1ft=24in(ft)/1ft, then theh ft units cancel and you get 24 in so the unit you want to cancel has to be on the bottom so
2. 2 gall to qt
2gal/1
gal has to be on bottom
4 quaret=1 gal
4qt/1gal
4qt/1gal times 2gal/1=8qt(gal)/gal=8qt
3. 1000 meters=1 kilometer
3000 times 1/1000=3
answer is 3km
4. 1000 gram=1kilogram
1500 times 1/1000=1.5
answer is 1.5kg
6, 500 cm to meter
100 cm=1meter
500 cm/100=5m
answer is 5m
7. 3 mile
1 mile=5280 ft
3 times 5280=15840 ft
8. 0.9 km
1000 m=1km
multiply
0.9 times 1000=900m
answe ris 900m
9. 24 in=2 ft=2/3yd
6yd=18ft=216in
10. a. 9in=9/12=3/4 ft
so find how many legnths and multiply the legnths by 3/4 ft
b. 4 tiies9=36
36/12=3 ft
answe ris 3 ft
