Question

Express as meters using decimals.
15 cm
6 cm
2 m 45 cm
9 m 7 cm
419 cm

Answer 1

(a)∵ 1 cm = \(\frac{1}{100}\) m
∴ 15 cm = \(\frac{1}{100}\)x 15 = 0.15 m

---

(b) ∵1 cm = \(\frac{1}{100}\) m
∴ 6 cm = \(\frac{1}{100}\) x 6 = 0.06 m

---

(c) ∵ 1 cm = \(\frac{1}{100}\) m
∴ 2 m 45 cm = 2 + \(\frac{1}{100}\) x 45 = 2.45 m

---

(d) ∵ 1 cm = \(\frac{1}{100}\) m
∴ 9 m 7 cm = 9 + \(\frac{1}{100}\) x 7 = 9.07 m

---

(e) ∵ 1 cm = \(\frac{1}{100}\) m
∴ 419 cm = \(\frac{1}{100}\) x 419 = \(\frac{419}{100}\) = 4.19 m
