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

### Instruction:
Dikembe wants to teach everyone at school about the importance of flossing, so he plans to bring enough packets of floss for everyone. There are 20 students in his class. Each student needs 1.5 yards of floss. He sees in the store that each packet of floss contains 35 yards. If he buys the least amount necessary, how much floss is left over?

### Response:
 Atahitaji kuleta uzi wa meno wa yadi 30 kwa sababu 20 x 1.5 = <<20*1.5=30>>30
Kifurushi kimoja cha uzi wa meno kinatosha kwa sababu 35 > 30
Atabakiwa na yadi 5 za uzi wa meno kwa sababu 35 - 30 = 5
