If the sum of three numbers is 456 and the first two numbers are 121.3 and 175.4 what is the average of the three numbers?

To find the average of the three numbers, first calculate the third number by subtracting the sum of the first two from the total sum: (456 - (121.3 + 175.4) = 456 - 296.7 = 159.3). Next, add all three numbers: (121.3 + 175.4 + 159.3 = 456). Finally, divide the total by 3 to find the average: (456 \div 3 = 152). Thus, the average of the three numbers is 152.
