2/5 by bus .2/1/2 motorcycle and walked the rest .if the whole journey was 47/3/5

Haya hapa masuluhisho ya swali lako:

Swali la 2: Safari ya Martha (Marekebisho)

• Kumbuka kuhusu swali: Kwa sababu ya uandishi, maneno "40/2/5" na "2/1/2" yamefasiriwa kama shughuli za kugawanya.

  • "40/2/5" imefasiriwa kama $40 \div 2 \div 5$.
  • "2/1/2" imefasiriwa kama $2 \div 1 \div 2$.
  • "47/3/5" imefasiriwa kama nambari mchanganyiko $47\frac{3}{5}$.

• Step 1: Tambua umbali uliosafiri kwa basi na pikipiki. Umbali aliosafiri kwa basi:

  $$40 \div 2 \div 5 = 20 \div 5 = 4 \text{ km}$$

  Umbali aliosafiri kwa pikipiki:

  $$2 \div 1 \div 2 = 2 \div 2 = 1 \text{ km}$$

• Step 2: Badilisha jumla ya safari kuwa sehemu isiyofaa. Jumla ya safari ni $47\frac{3}{5}$ km.

  $$47\frac{3}{5} = \frac{(47 \times 5) + 3}{5} = \frac{235 + 3}{5} = \frac{238}{5} \text{ km}$$

• Step 3: Tafuta umbali aliotembea. Umbali aliotembea ni jumla ya safari kutoa umbali aliosafiri kwa basi na pikipiki.

  $$x = \frac{238}{5} - 4 - 1$$ $$x = \frac{238}{5} - 5$$

  Ili kutoa sehemu hizi, tunahitaji madhehebu ya kawaida. Badilisha 5 kuwa $\frac{25}{5}$:

  $$x = \frac{238}{5} - \frac{25}{5}$$ $$x = \frac{238 - 25}{5}$$ $$x = \frac{213}{5}$$

• Step 4: Badilisha jibu kuwa nambari mchanganyiko au desimali.

  $$x = 42\frac{3}{5} \text{ km}$$ $$x = 42.6 \text{ km}$$

  Umbali aliotembea ni $\text{42.6 km}$.
