20:19 Math 7 - Module 2B - Lesson 13 Day 2

Review how to Convert
1) Decimals to Fractions
2) Fractions to Decimal by rewriting Fractions with a Denominator with a Base of 10

19:11 Math 7 - Module 2B - Lesson 13 Day 1 - Exercise 2

Convert a Fraction to a Decimal

28:14 Pre-Algebra 6.9 Indirect Measurements

Setting up Proportions with Corresponding Parts to Solve and Find a missing measurement

42:22 Math 7 - Lesson 12

How is Multiplication related to Division?
Identify the Dividend, Divisor, and Quotient.
How are the Dividend and Divisor related to Numerator and Denominator?

50:51 Pre-Algebra: 6.8 - Dilations

Transformation #3 - Dilation
1) Find new points for Image
2) Graph Image
3) Find Scale Factor of Image
4) If given Image and SF, find Original Points

54:18 Pre-Algebra - 6.7: Similar Figures

Finding Measures of Similar Figures by
1) Using Proportions to match Corresponding Parts
2) Setting it up as an Equation y = kx
y is what you want
k is the scale factor
x is what you have

if scale factor, SF is <1 you have a reduction
if scale factor, SF is >1 you have an enlargement

53:02 Math 7 - Module 2B - Lesson 11

The Rules for Multiplication

Note:
I misspoke at the end. I boofed.
-1 x -1 = (positive) 1
I don't know why I said = 0
(ACTUALLY I DO - BUT....)
