Question

Multiply and express as a mixed fraction :
(a) 3 × 5 \(\frac{1}{5}\)
(b) 5 × 6 \(\frac{3}{4}\)
(c) 7 × 2 \(\frac{1}{4}\)
(d) 4 × 6 \(\frac{1}{3}\)
(e) 3 \(\frac{1}{4}\) × 6
(f) 3 \(\frac{2}{5}\) × 8

Answer 1

(a) 3 × 5 \(\frac{1}{5}\)= 3 × \(\frac{26}{5}\)= \(\frac{78}{5}\) = 15 \(\frac{3}{5}\)

---

(b) 5 × 6 \(\frac{3}{4}\) = 5 × \(\frac{27}{4}\) = \(\frac{135}{4}\)= 33 \(\frac{3}{4}\)

---

(c) 7 × 2\(\frac{1}{4}\)= 7 × \(\frac{9}{4}\)= \(\frac{63}{4}\) = 15\(\frac{3}{4}\)

---

(d) 4 × 6 \(\frac{1}{3}\)= 4 × \(\frac{19}{3}\) = \(\frac{76}{3}\) = 25 \(\frac{1}{3}\)

---

(e) 3 \(\frac{1}{4}\) × 6 = \(\frac{13}{4}\) × 6 = \(\frac{78}{4}\) = \(\frac{39}{2}\) = 19\(\frac{1}{2}\)

---

(f) 3 \(\frac{2}{5}\) × 8 = \(\frac{17}{5}\) × 8 = \(\frac{136}{5}\) = 27 \(\frac{1}{5}\)
