Answer 1

#include <iostream>


using namespace std;




int main() {
	float cement=30000;
	float sand=50000;
	float gravel=17500;
	float water=3000;


	//calculate and display the amount of sand in a real number and a percentage of the total mass of concrete. 
	float totalMass=cement+sand+gravel+water;
	float percentageTotalMass=(sand/totalMass)*100.0;
	float percentageCementTotalMass=(cement/totalMass)*100.0;
	cout<<"The amount of sand in a real number: "<<sand<<"\n";
	cout<<"A percentage of the total mass of concrete: "<<percentageTotalMass<<"%\n";
	//The amount of water in real number,and a percentage of the amount of cement
	cout<<"The amount of water in a real number: "<<water<<"\n";
	cout<<"A percentage of the amount of cement: "<<percentageCementTotalMass<<"%\n";


	cin>>cement;
	return 0;
