    1. 2,0475
    2. 4,0475
    3. 20,475
    4. 40,475
    5. 200,475
    Jawaban : c

    1% dari 455 = 4,55

    Berarti 4,5%-nya = 4,5 x 4,55 = 20-an

  2. <p>Jika 𝑥 = \(\frac{1}{25}\) dan 𝑦 = 25%, maka ...</p>
    1. 𝑥 = 𝑦
    2. 𝑥 > 𝑦
    3. 𝑥 < 𝑦
    4. 𝑥 ≥ 𝑦
    5. 𝑥 ≤ 𝑦
    Jawaban : c

    𝑥 = \(\frac{1}{25}\) = \(\frac{1}{25}\) x \(\frac{4}{4}\) = \(\frac{4}{100}\)

    𝑦 = 25% = \(\frac{25}{100}\)

    Maka 𝑥 < 𝑦
