Operasi hitung berikut benar, kecuali …. a. 54 : (60 + (-6)) = 1 b. (5 * 4) * (5-3) = 40 c. 11 – 5 x 2 = 21 1. (7-2) * (2 + 3) = 25

Penjelasan dengan langkah-langkah:

a)

54 : (60 + (-6) = 1

54 : 54 = 1

1 = 1 (Benar)

b)

(5 * 4) * (5 – 3) = 40

20 * 2 = 40

40 = 40 (Benar)

c)

11 – 5 × 2 = 21

11 – 10 = 21

1 = 21 (Salah)

d)

(7 – 2) * (2 + 3) = 25

5 * 5 = 25

25 = 25 (Benar)

Kecuali = (C)
