Answer 1

#include <stdio.h>

double GetPercentage(float num1, float num2) {
    return (num1 / num2) * 100.0;
}

int main(void) {
    printf("30 is %.2f%% of 40\n", GetPercentage(30, 40));

    printf("40 is %.2f%% of 30\n", GetPercentage(40, 30));

    printf("20 is %.2f%% of 35\n", GetPercentage(20, 35));

    return 0;
