KnowledgeBoat · Accepted Answer

(i) By cross multiplication, 3 × 40 = 120 and 10 × 12 = 120 Here, the cross products are equal. Hence, and are equivalent fractions. (ii) By cross multiplication, 5 × 48 = 240 and 8 × 30 = 240 Here, the cross products are equal. Hence, and are equivalent fractions. (iii) By cross multiplication, 4 × 20 = 80 and 6 × 30 = 180 Here, the cross products are not equal. Hence, and are not equivalent fractions. (iv) By cross multiplication, 7 × 11 = 77 and 13 × 5 = 65 Here, the cross products are not equal. Hence, and are not equivalent fractions.
