ИЛИ:

func main() {
    var steps, dancers, days float64
    fmt.Scanln(&steps)
    fmt.Scanln(&dancers)
    fmt.Scanln(&days)

    dayStepPercent := math.Ceil(steps / days / steps * 100)
    dancerStepPercent := dayStepPercent / dancers

    if dayStepPercent < 13 {
        fmt.Printf("Yes, they will succeed in that goal! %.2f%%.\n", dancerStepPercent)
