This document contains notes from a math lesson including an assignment, warm-up problems, and information about ratios. It discusses how to write ratios using words, fractions, colons, and decimals and emphasizes that ratios should always be reduced. Examples are provided from the lesson on page 188 of the textbook. The lesson covered evaluating expressions, expanding polynomials, factoring expressions, inverse operations, properties of equilateral triangles, and different ways to write ratios.

Lesson 29 Warm­Up:
1) Evaluate x2 ­ 2x, when x = 5.
2) Expand: 3(x + r + 5)
3) Factor: 4x + 6y
4) What is the multiplicative inverse of 2 1/2?
5) If a triangle is an equilateral triangle, then each angle

Lesson 29
*ratio – a comparison of 2 numbers by division
FYI...
We can write ratios 4 ways:
­with the word "to" ­­> 3 to 4
­as a fraction ­­> 3/4
­with a colon ­­> 3:4
­as a decimal ­­> 0.75
**Ratios should ALWAYS be reduced!!
