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

### Instruction:
Donna cut her pizza into 12 slices and ate half for lunch.  She ate 1/3 of the remaining pizza for dinner.  How many slices are left for Donna's lunch tomorrow?

### Response:
 Pizza yake ina vipande 12 na alakula 12/2 = <<12/2=6>>6 vipande kwa chakula cha mchana.
Baada ya chakula chake cha kwanza, anabakiwa na vipande 12-6 = <<12-6=6>>6.
Alakula 1/3 ya pizza kwa chakula cha jioni, hivyo alakula 1/3*6 = <<1/3*6=2>>2 vipande.
Anabakiwa na vipande 6-2 = <<6-2=4>>4 kwa chakula cha mchana kesho.
