Integrating Essential Skills questions test your ability to:
- Apply multiple math topics in one problem
- Interpret real-world scenarios (e.g., distance, finance, percentages)
- Use logical reasoning and problem-solving steps
- Read carefully and decide what’s relevant
Ratios, Proportions, and Percentages
Key Concepts
- Percent increase/decrease
- Proportions in real-world contexts (e.g., scale maps, recipes)
- Unit conversions (e.g., feet to inches, minutes to seconds)
Skills Tested
- Setting up correct proportions
- Solving for unknowns in context
- Applying percentage formulas
Example Question
A price increases from $80 to $100. What is the percent increase? A. 20% B. Answer: 25% (Increase = 20; \frac{20}{80} = 0.25 = 25%)
Rates, Speed, and Work Problems
Key Concepts
- Distance = rate × time
- Inverse variation for work problems
- Combining rates (e.g., people working together)
Skills Tested
- Solving using algebraic setup
- Converting units (e.g., hours to minutes)
- Interpreting multi-step word problems
Example Question
If Jack paints a wall in 4 hours and Jill in 6 hours, how long will it take them working together? A. 2.4 hours B. Answer: 2.4 hours (Use \frac{1}{t} = \frac{1}{4} + \frac{1}{6} \Rightarrow t = \frac{12}{5} = 2.4)
Interpreting Tables, Charts, and Graphs
Key Concepts
- Reading real-world data (cost charts, schedules, tables)
- Analyzing multi-variable data
- Drawing conclusions based on visual info
Skills Tested
- Translating visual data into math expressions
- Identifying trends or calculations from raw info
- Cross-referencing multiple data points
Example Question
A car rental chart shows: $25/day plus $0.10/mile. What’s the total cost for a 3-day rental with 200 miles? A. $55 B. Answer: $85 (3 × 25 = 75 + (0.10 × 100) = $85)
Geometry in Real-Life Applications
Key Concepts
- Area, perimeter, and volume in construction, packing, landscaping
- Using geometric shapes in measurement scenarios
Skills Tested
- Converting units (e.g., square feet to square inches)
- Setting up equations for area/cost/time
- Applying volume and area formulas
Example Question
You need to carpet a room 12 ft by 10 ft. Carpet costs $3 per square foot. What is the total cost? A. $300 B. Answer: $360 (Area = 120 ft² × $3 = $360)
Multi-Step Algebraic Word Problems
Key Concepts
- Combining equations, formulas, or logic steps
- Using variables to represent unknowns
- Interpreting word problems with multiple layers
Skills Tested
- Translating words into expressions/equations
- Keeping track of units and constraints
- Solving for unknowns in context
Example Question
A phone plan charges $40/month plus $0.05 per text. If you paid $55, how many texts did you send? A. 300 B. Answer: 300 (Let x = # of texts: 40 + 0.05x = 55 \Rightarrow x = 300)
