Asked by Lwendo

Can you help me please? The question is : The mean of three numbers is 2 and 1/2. Two of the numbers are 1 and 3/4 and 1 and 3/10. Work out the third number?

If you start off multiplying the mean by 3, you'll get the sum of the numbers = 7.5 This means all three numbers add up to 7.5. So if you take the other two numbers away from 7.5 you'll have the third number. 7.5 - 1.75 = 5.75 5.75 - 1.3 = 4.45. The third number is 4.45
