ok. A caterer is counting cakes to determine whether more are needed to finish serving the wedding guests. One table has five and one third cakes, and the other table has one eighth of a cake. Estimate the number of remaining cakes by rounding each term to the nearest whole number. Answer choices are eight five six and four WHICH ONE?? its either five or six

5 1/3 + 1/8 is the same as 16/3 + 1/8. Multiply top and bottom to get a common denominator (8/8)*(16/3) + (3/3)*(1/8) becomes 128/24 + 3/24 You can now add them You should get 131/24, which then can be broken down to 5 11/24. You should be able to tell the nearest whole number now.

I would have said to do the following: 5 1/3 = 5 8/24 + 1/8 = 3/24 _______________ To get 24 as the lowest common denominator, just multiply 3x8. With that known, then add the fractions together. In this particular problem, no reduction to lowest terms is needed. Thus saving a step in solving the problem. 5 8/24 + 3/24 ______ 5 11/24 or a total of 6 cakes when rounded up to the next whole number.
