Lesson 6-10 for exercise sets.

For exercises 5 and 6, use dimensional analysis to make each conversion.

Identify the conversion factor for each.

1.4 yards to feet 2.36 fl oz to cups 3.2640 ft to miles 4.24 pints to gallons

Use dimensional analysis to determine the unit price.

5.64 fl oz for $2.90; Find the price per gallon.

6.2 tons for $840; Find the price per pound.

7.If $1 0.76 Euro, how many Euros would you get if you were

to exchange $80?

8.If $1 0.76 Euro, how many U.S. dollars would you get if you were

to exchange 80 Euros?

9.Discuss and Write Explain how you would use dimensional analysis to convert

1 foot to centimeters using 2.54 cm1 in. as the conversion factor.

You can use dimensional analysis to convert between two different currencies.

If $1 0.76 Euro, how many Euros would you get if you were to exchange $25?

To convert from one currency to another, multiply one

currency by the , the conversion factor.

$25  • Multiply $25 by the number of Euros in $1.
