per cent means per hundred 56 out of 75 = approx 79 out of 100 = approx 79 % (approx 79 percent) Another way to do a quick estimate is to find a multiple of 100. In this case 75 times 4 would be 300. 4 time 56 is 224. Divide 224 by 3 (the number of hundreds) and you get about 75%

If: x+y = 79 Then: y = 79-x If: xy = 1288 Then: x(79-x) = 1288 and it follows that: 79x-x2-1288 = 0 Solving the above quadtratic equation gives x a value of 23 or 56 So the values are x = 23 and y = 56 Check: 23+56 = 79 and 23*56 = 1288
