Answer 1

Jawab:

Penjelasan dengan langkah-langkah:

5 / (1/8 + 1/6 + 1/4 + 1/12 + 1/4)

5 / (3/24 + 4/24 + 6/24 + 2/24 + 6/24)

5 / 21/24

5 x 24/21 = 120/21 = 40/7 = 5 5/7

Jawabannya adalah A

Answer 2

Materi : Data dan Statistika

Rumus Rata - Rata Harmonis

H = n/Σ( 1/x-ni )

n = Banyak Data

Σ( 1/x-ni ) = penjumlahan semua data dalam bentuk nilai pecahan. Misal 2,3,4 => ( ½ + ⅓ + ¼ )

Langsung Saja

Banyak Data = 5

---

H = 5/( ⅛ + ⅙ + ¼ + 1/12 + ¼ )

H = 5/( 3/24 + 4/24 + 6/24 + 2/24 + 6/24 )

H = 5/( [ 3 + 4 + 6 + 2 + 6 ]/24 )

H = 5/( 21/24 )

H = 5/( ⅞ )

H = 5 . 8/7

H = 40/7 [ 35 => 5 ]

H = 5 + 5/7 { a. }

Semoga bisa membantu
