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

### Instruction:
A club with 30 members ordered fruit juices. Two-fifths of them ordered lemon juice. One-third of the remaining members ordered mango juice, and the rest ordered orange juice. How many members ordered orange juice?

### Response:
 30 x 2/5 = <<30*2/5=12>>12 wanachama waliagiza maji ya limau.
Hivyo, 30 - 12 = <<30-12=18>>18 wanachama hawakuagiza maji ya limau.
Kwa kuwa 1/3 ya waliobaki waliagiza maji ya embe, basi 18 x 2/3 = <<18*2/3=12>>12 wanachama waliagiza maji ya embe.
Hivyo, 18 - 12 = <<18-12=6>>6 wanachama waliagiza maji ya chungwa.
