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

### Instruction:
Sandro has six times as many daughters as sons. If he currently has three sons, how many children does he have?

### Response:
 Ikiwa Sandro ana watoto wa kiume watatu, idadi jumla ya binti, mara sita ya idadi ya watoto wa kiume, ni 3 watoto wa kiume * 6 binti/kijana = <<3*6=18>>18 binti.
Idadi jumla ya watoto ambao Sandro ana ni binti 18 + watoto wa kiume 3 = <<18+3=21>>21.
