(ii) 36 ÷ 0.2
(iii) 3.25 ÷ 0.5
(iv) 30.94 ÷ 0.7
(v) 0.5 ÷ 0.25
(vi) 7.75 ÷ 0.25
(vii) 76.5 ÷ 0.15
(viii) 37.8 ÷ 1.4
(ix) 2.73 ÷ 1.3

Answer 1

(i) 7 ÷ 3.5 = 7 ÷ $\frac{35}{10}$ = 7 × $\frac{10}{35}$= 2

---

(ii) 36 ÷ 0.2 = 36 ÷ $\frac{2}{10}$ = 36 × $\frac{10}{2}$= 180

---

(iii) 3.25 ÷ 0.5 = $\frac{325}{100}$ ÷ $\frac{5}{10}$ = $\frac{325}{100}$ × $\frac{10}{5}$ = $\frac{65}{10}$= 6.5

---

(iv) 30.94 ÷ 0.7 = $\frac{3094}{100}$ ÷ $\frac{7}{10}$ = $\frac{3094}{100}$ × $\frac{10}{7}$ = $\frac{442}{10}$ = 44.2

---

(v) 0.5 ÷ 0.25 = $\frac{5}{10}$÷ $\frac{25}{100}$= $\frac{5}{10}$ × $\frac{100}{25}$ = 2

---

(vi) 7.75 ÷ 0.25 = $\frac{775}{100}$ ÷ $\frac{25}{100}$ = $\frac{775}{100}$ × $\frac{100}{25}$ = 31

---

(vii) 76.5 ÷ 0.15 =$\frac{765}{100}$÷ $\frac{15}{100}$ = $\frac{765}{10}$ × $\frac{100}{15}$ = 510

---

(viii) 37.8 ÷ 1.4 = $\frac{378}{100}$ ÷$\frac{14}{10}$= $\frac{378}{18}$ ×$\frac{10}{14}$ = 27

---

(ix) 2.73 ÷ 1.3 = $\frac{273}{100}$ ÷ $\frac{13}{10}$ = $\frac{273}{100}$ × $\frac{10}{13}$ = $\frac{21}{10}$= 2.1
