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
