Question

Find:
(i) 0.2 × 6
(ii) 8 × 4.6
(iii) 2.71 × 5
(iv) 20.1 × 4
(v) 0.05 × 7
(vi) 211.02 × 4
(vii) 2 × 0.86

Answer 1

(i) 0.2 × 6 = \(\frac{2}{10}\) × 6 = \(\frac{12}{10}\)= 1.2

---

(ii) 8 × 4.6 = 8 × \(\frac{46}{10}\)= \(\frac{368}{10}\) = 36.8

---

(iii) 2.71 × 5 = \(\frac{271}{100}\) × 5 = \(\frac{1355}{100}\) = 13.55

---

(iv) 20.1 × 4 = \(\frac{201}{10}\) × 4 = \(\frac{804}{10}\) = 80.4

---

(v) 0.05 × 7 = \(\frac{5}{100}\) × 7 = \(\frac{35}{100}\) = 0.35

---

(vi) 211.02 × 4 = \(\frac{21102}{100}\) × 4 = \(\frac{84408}{100}\) = 844.08

---

(vii) 2 × 0.86 = 2 × \(\frac{86}{100}\) = \(\frac{172}{100}\) = 1.72
