Big Idea 1 - Lesson 1.5

FRQ 1

public static double avgInt(int a, int b) {
    return ((double) a + b) / 2;
}

System.out.println(avgInt(2, 3));  
System.out.println(avgInt(5, 6)); 
System.out.println(avgInt(4, 8)); 

2.5
5.5
6.0

FRQ 2

public static double percent(int correct, int total) {
    return ((double) correct / total) * 100;
}
System.out.println(percent(8, 10));  

80.0

FRQ 3

public static int safeMod(int a, int b) {
    if (b == 0) {
        return 0;
    }
    return a % b;
}

System.out.println(safeMod(10, 3));  // 1
System.out.println(safeMod(7, 5));   // 2
System.out.println(safeMod(7, 0));   // 0 (safe)
