Evaluate: 12.92 - 2.36 / 0.068 + 0.012

Haya hapa majibu ya swali hilo:

Hesabu za Desimali

• Konteksi: $\frac{2.92 - 2.36}{0.068 + 0.012}$
• Step 1: Kokotoa nambari (numerator) kwanza. $$2.92 - 2.36 = 0.56$$
• Step 2: Kokotoa denomineta (denominator) kwanza. $$0.068 + 0.012 = 0.080 = 0.08$$
• Step 3: Gawanya nambari kwa denomineta. Ili kurahisisha, unaweza kuzidisha nambari na denomineta kwa 100 ili kuondoa desimali. $$\frac{0.56}{0.08} = \frac{0.56 \times 100}{0.08 \times 100} = \frac{56}{8}$$
• Step 4: Fanya mgawanyiko. $$\frac{56}{8} = 7$$
• Jibu: Thamani ni $\mathbf{7}$.
