5 dulu yah kak Pembahasan

Bunga (B) = Total Tabungan - Modal

Modal (M) = Rp800.000

Suku Bunga (p) = 9% pertahun

Waktu = W

Total Tabungan = Rp920.000

B space equals space M space cross times space W space cross times space p 920000 space minus space 800000 space equals space 800000 cross times fraction numerator b u l a n over denominator 12 end fraction cross times 9 over 100 120000 space equals space 800000 cross times fraction numerator b u l a n over denominator 12 end fraction cross times 9 over 100 120000 space equals space 7200000 over 1200 cross times b u l a n b u l a n space equals space 144000000 over 7200000 b u l a n space equals space 20

Jadi, lama kakak menabung adalah 20 bulan.

6Diketahui

☑ bruto = 25 kg

☑ tarra = 0,5 kg

DItanya :

a). Persentase Netto

b). Persentase Tara

Jawaban :

a). Persentase Netto

↪Tentukan Nilai Netto

Netto = bruto - Tara

Netto = 25 - 0,5

Netto = 24,5 kg

Maka, persentase Netto :

= (Netto/bruto) x 100%

= (24,5/25) x 100%

= 98% ✔

b). persentase Tara

= (Tara/Bruto) x 100%

= (0,5/25) x 100%

= 2 % ✔
