### Instruction:
On her birthday, Avianna bought red candles and blue candles in the ratio of 5:3. If Avianna had 45 red candles on her birthday, how many blue candles did she have?

### Response:
 Ikiwa uwiano wa mishumaa nyekundu na mishumaa buluu ni 5:3, basi kuna mishumaa 5 + 3 = <<5+3=8>>8 jumla.
Kuna mishumaa 45 x 3/8 = <<45*3/8=15>>15 buluu.
