Question

Multiply and reduce to lowest form (if possible) :
(i) \(\frac{2}{3}\) × 2 \(\frac{2}{3}\)
(ii) \(\frac{2}{7}\) × \(\frac{7}{9}\)
(iii) \(\frac{3}{8}\) × \(\frac{6}{4}\)
(iv) \(\frac{9}{4}\) × \(\frac{3}{5}\)
(v) \(\frac{1}{3}\)× \(\frac{15}{8}\)
(vi) \(\frac{11}{2}\) × \(\frac{3}{10}\)
(vii) \(\frac{4}{5}\) × \(\frac{12}{7}\)

Answer 1

(i) \(\frac{2}{3}\) × 2 \(\frac{2}{3}\) = \(\frac{2}{3}\) × \(\frac{8}{3}\) = \(\frac{16}{9}\) = \(\frac{17}{9}\)

(ii) \(\frac{2}{7}\) × \(\frac{7}{9}\) = \(\frac{2}{9}\)

---

(iii) \(\frac{3}{8}\) × \(\frac{6}{4}\) = \(\frac{9}{16}\)

---

(iv) \(\frac{9}{5}\) × \(\frac{3}{5}\) = \(\frac{27}{5}\)= 1 \(\frac{2}{25}\)

---

(v) \(\frac{1}{3}\) × \(\frac{15}{8}\) = \(\frac{5}{8}\)

---

(vi) \(\frac{11}{2}\) × \(\frac{3}{10}\)= \(\frac{33}{20}\) = 1 \(\frac{13}{20}\)

---

(vii) \(\frac{4}{5}\)× \(\frac{12}{7}\) = \(\frac{48}{35}\) = 1 \(\frac{13}{35}\)
