Answer:Step-by-step explanation:You need an x value to determine what number to multiply that will give you three numbers that are in the ratio of 3:1:4Let the number = xSet the equation up as 3x + x + 4x = 5003x + x + 4x = 500 Combine the left8x = 500 Divide both sides by 8x = 500/8 Divide by 8. x = 62.5So 3x = 3*62.5 = 187.51x = 1 * 62.5 = 62.54x = 4 * 62.5 = 250 The total should be 500
