Use the order of operations to simplify this expression. Express your answer in simplest form. 1/4 + 1/2 ÷ 3/8

Answer 1

Looking at   1/4 + 1/2 ÷ 3/8    we see that the division must be done first:

1/4 + (1/2) / (3/8) = 1/4 + 4/3
                                                      3 + 16
Combining 1/4 and 4/3, we get  ------------ = 19/12
                                                          12
