(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
