Give me at least one example of real application of real numbers grade 7
Answer (1)
Answer:Real numbers are all the numbers that can be found on the number line. They include:Whole numbers (0, 1, 2, 3…)Integers (… -3, -2, -1, 0, 1, 2 …)Fractions and decimals (like ½, 2.75, -3.6)Irrational numbers (like √2 or π, which cannot be written as exact fractions).In short, real numbers are the numbers we use in real life for counting, measuring, and calculating.Examples of Real Application:1. Let’s say Maria went to the market and bought 2.5 kilograms of apples. Each kilo costs ₱120. To find how much she needs to pay, she multiplies: 2.5 times 120 = 300. So, Maria pays ₱300. Here, 2.5 (a decimal number) and 120 (a whole number) are both real numbers.2. Temperature: When the weather report says it’s -3°C in Baguio at dawn, the “-3” is a negative real number.3. Distance: A runner finished a marathon in 42.195 kilometers—that’s a decimal real number.4. Money: If you have ₱1000 and spend ₱325.75, the subtraction involves real numbers.5. Time: A class lasts 1.5 hours—that’s also a real number (a fraction in decimal form).
