Here’s a structured and student-friendly table that highlights real-life applications of high school math with examples:

Application	Description	Example	Solution Steps
Social Media Analytics	Measure engagement or growth rates.	A user has 500 followers and receives 125 likes on a post. What is the like-to-follower ratio?	1. Write the ratio: 125 : 500. 2. Simplify: $\frac{125}{500}$ = $\frac{1}{4}$ Like-to-follower ratio = 1:4.
Budgeting	Allocate income proportionally.	A student earns $400 per month and allocates 50% for expenses, 30% for savings, and 20% for entertainment. How much goes into each category?	Calculate each portion: Expenses: 400 $\times$ 0.5= 200, Savings: 400 $\times$ 0.3 = 120, Entertainment = 400 $\times$ 0.2 = 80.
Cooking and Recipes	Adjust ingredient quantities for more servings.	A recipe for 4 people requires 2 cups of flour. How much flour is needed for 10 people?	1. Set up a proportion: $\frac{2}{4}$ = $\frac{x}{10}$. 2. Cross-multiply: 4𝑥=20 3. Solve: 𝑥=5. Flour needed = 5 cups.
Health and Fitness	Calculate body-related metrics.	A person weighs 60 kg and is 1.6 m tall. What is their Body Mass Index (BMI)? $\text{Formula}$ : $\text{BMI}$ = $\frac{\text{weight}}{\text{height}^2}$	1. Plug in values: $\frac{60}{1.6^2}$ 2. Calculate: $1.6^2$= 2.56, $\frac{60}{2.56}$ $\approx$ 23.44, BMI = 23.44
Blueprints and Models	Scale dimensions for construction.	A model car is built to a scale of 1:20. If the car’s length on the model is 15 cm, what is the actual car’s length?	1. Set up a proportion: $\frac{1}{20}$ = $\frac{15}{x}$. 2. Cross-multiply: 𝑥=15 $\times$ 20=300. Actual length = 300 cm (3 meters).
Discounts	Find the sale price after a discount.	A t-shirt costs $50, and there is a 20% discount. What is the sale price?	1. Calculate discount: 50 $\times$ 0.2 = 10. 2. Subtract: 50 $−$ 10 = 40 Sale price = $40.
Maps	Use map scales for real distances.	A map scale is 1 : 1,00,000. If the distance between two cities is 5 cm on the map, what is the actual distance in kilometers?	1. Convert cm to actual: 5 $\times$ 1,00,000 = 5,00,000 cm. 2. Convert to kilometers: 5,00,000 $\div$ 1,00,000 =5. Actual distance = 5 km.
Photography	Maintain aspect ratios for resizing images.	An image has a width of 1200 px and a height of 800 px. If resized to a width of 600 px, what will the new height be?	1. Set up a proportion: $\frac{1200}{800}$ = $\frac{600}{x}​$. 2. Cross-multiply: 1200𝑥 =4,80,000 3. Solve: 𝑥= 400. New height = 400 px.
Sports	Calculate performance metrics.	A basketball player scored 48 points in 12 games. What is the average points per game?	1. Write the ratio: $\frac{48}{12}$. 2. Simplify: $\frac{48}{12}$ = 4. Average points per game = 4.
Event Planning	Plan catering proportionally to guests.	For 50 guests, 10 pizzas are needed. How many pizzas are required for 120 guests?	1. Set up a proportion: $\frac{10}{50}$ = $\frac{x}{120}$. 2. Cross-multiply: 50𝑥 = 1200. 3. Solve: 𝑥 = 24. Pizzas needed = 24.
