Question

Express as kg using decimals.

1. 2 g
2. 100 g
3. 3750 g
4. 5 kg 8 g
5. 26 kg 50 g

Answer 1

(a) ∵ 1 g = \(\frac {1}{1000}\) kg

∴ 2 g = \(\frac {1}{1000} \times 2\) = 0.002 kg

---

(b) ∵ 1 g = \(\frac {1}{1000}\) kg

∴ 100 g = \(\frac {1}{1000} \times 100 \) = 0.1 kg

---

(c) ∵ 1 g = \(\frac {1}{1000}\) kg

∴ 3750 g = \(\frac {1}{1000} \times 3750\) = 3.750 kg

---

(d) ∵ 1 g = \(\frac {1}{1000}\) kg

∴ 5 kg 8 g = 5 + \(\frac {1}{1000} \times 8\) = 5.008 kg

---

(e) ∵ 1 g = \(\frac {1}{1000}\) kg

∴ 26 kg 50 g = 26 + \(\frac {1}{1000} \times 50\) = 26.050 kg
