Mr. Gallegos made a batch of muffins. He gave 11/21 of the batch to his neghbors and ate 1/8 of the batch himself. Which is the best estimation of the fraction of the batch that was left?

The answer to your question is There were 59/168 muffins left.

Step-by-step explanation:

Data

Initial amount of muffins = 1

Amount of muffins given to his neighbors = 11/21

Amount of muffins eaten = 1/8

Amount of muffins left = ?

Process

1.- Subtract the amount of muffins given to the neighbors and the amount of muffins eaten to the initial amount of muffins.

             1 - 11/21 - 1/8 =

-Look for the greatest common factor

                    21   8    2

                    21   4    2

                    21   2    2

                    21    1    3

                      7         7

                      1

   GCF = 2 x 2 x 2 x 3 x 7

           = 168

-Solve the arithmetical operation

              1 - 11/21 - 1/8 = (168 - 88 - 21) / 168

                                   = 59/168

-Conclusion

There were 59/168 muffins left.
