you can easily understand converstion factors with a rule of thee
Step 1
a) Convert 9.85 L to gallons.
Let
x number of gallons
if
1 gallon = 3.78 liters
xgallon = 9.85 liters
Step 2
do the relation and solve for x
so, 9.85 L= 2.6 gallons
b)How many miles are in 25 km?
1 mile = 1.61 kilometer
Let
x number of miles
if
1 mile = 1.61 km
x mile = 25 Km
Step 2
do the relation and solve for x
so, 25 Km= 15.52 miles
c)If a person has a mass of 60 kilograms, what is his mass in tons?
if
2,000 pounds = 1 ton
2.20 pounds = 1 kilogram
then
first, convert kilogram to pounds, then convert pounds to tons?
Let x, number of pounds
2.20 pounds = 1 kilogram
x pounds = 60 Kilogram
so , 60 Kg=132 pounds
Now, convert pounds to tons
Let x, number of tons
2,000 pounds = 1 ton
132 Pounds = x ton
so, 60 Kg =0.066 tons
I hope this helps you
