Due Monday, May 4
section 2.1
problems:

• 1
• 2 - All ratios written as fractions must be in most reduced form.
• 5a, 5b, 5c, 5d
• 6 - When writing a ratio you must pay attention to the units. For example: if the units are g/Kg=g/Kg that is OK. However, you can also write this as g/g=Kg/Kg because the units cancel each other so both sides of the ratio are unit-less, which is the same (note: the numerator and denominator must represent the same thing). Problem 6c, you will need to change some units to make this problem work.
• 7a, 7b - Remember that every proportion can be written in 4 different ways.
• 8
• 9
• 10
• 11
