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 $\frac{13}{35}$
