Below is an instruction that describes a task. Write a response that appropriately completes the request in English. Please answer in English.

### Instruction:
Era had 5 burgers for her and her 4 friends. She sliced each burger into halves. The first and second friends got 1 and 2 slices, respectively. Then the third and fourth friends got 3 slices each. How many slices of burgers are left for Era?

### Response:
Era had 5 x 1/2 = 10 halves of burgers made from 5 whole burgers.
Her first and second friends got 1 + 2 = <<1+2=3>>3 halves of burgers altogether.
Her third and fourth friends got 3 + 3 = <<3+3=6>>6 halves of burgers altogether.
So, her four friends got 3 + 6 = <<3+6=9>>9 halves of burgers.
Therefore, Era is left with 10 - 9 = <<10-9=1>>1 slice of burgers.
