Check your work and Answers by following along.
If you are still having issues after the video,
form questions to ask during class or Academic Support
Math 7 - Module 1D - Lesson 18
Finding CORRESPONDING Lengths
(by finding) the Scale Factor (SF)
Original Measurement X Scale Factor = NEW Measurement
Pre-Algebra - 4.6 Writing Equations
Be able to write an equation (2-Step) given information from a word problem and solve it.
Solving a 2-Step Equation:
(Pre-Step 1) Simplify, if possible, one-side of the equation - by combining like terms, distributing, etc
(Step 1) Eliminate the Constant from the side with the Variable - Additive Inverse
(Step 2) Eliminate the Coefficient - Multiplicative Inverse
Math 7 - Module 1D - Lesson 17 Problem Set Worked out
An explanation and working out of the steps for the problem set.
Check and compare your work.
Still unsure or lost, ask questions during class or Academic Support.
Pre-Algebra - 4.5 Day 2: More 2-Step Equations Practice
(check first - if you can simplify one side of the equation by combining LIKE Terms - if possible)
1) How to you eliminate the Constant? (set it to ZERO by using the Additive Inverse)
2) How to you eliminate the Coefficient? (set to ONE by using the Multiplicative Inverse)
Math 7 - Module 1D - Lesson 17
How do you find the SCALE FACTOR?
How do you use the Scale Factor, SF to show a drawing is a scale drawing/proportional drawing or not?
Given the Scale Factor, SF and the Original Measurements/Length/Distance,
draw the NEW image as a Reduction or Enlargement based on the Scale Factor.
Pre-Algebra - 4.5: Solving 2-Step Equations
Solve the Algebraic Equation (Isolate the variable)
1) Zero out the Constant (add or subtract to both sides of the "equal sign")
2) Convert the Coefficient to One (multiply by the multiplicative inverse)
Math 7 - Module 1D - Lesson 16
What is the Scale?
Pre-Algebra: Simplifying an Expression
Follow the Rules of GEMDAS aka the Order of Operations to simplify an expression
Distributing to eliminate grouping symbols
Sorting terms by Like Terms in order to Combine Like Terms
Pre-Algebra: Identifying Terms and Parts of an Expression
Separate the Expression into Terms to work with
Be able to Identify and Label the:
This exercise helps for you to see that you can only combine LIKE TERMS
Math 7 - Simplifying a Complex Ratio
Simplifying a Complex Ratio aka a Complex Fraction.
A Complex Ratio is a Ratio to a Ratio
To Simplify a Complex Ratio, convert the complex ratio into a division expression
The division expression will be dividing two fractions
Dividing two fractions is to
convert the division into multiplication
and multiply by the Reciprocal aka the Multiplicative Inverse
Math 7 - Finding the Unit Rate
Finding the Unit Rate is making an Equivalent Ratio where the Denominator is 1.
"per" mean "over 1" or "to 1"
Math 7 - Writing a Ratio
Given a story with information/ data, write a ratio from the desired relationship of two numbers.
Simplifying the ratio to a Simplified Fraction.
Math 7 - Equivalent Ratios, Percent to Fraction, Percent of a Number
