Find the product: 2 3 × 4 5

Given, 2 3 × 4 5 We know that, a b × c d = a × c b × d Thus, 2 3 × 4 5 = 2 × 4 3 × 5 = 8 15 Hence, the required answer is 8 15 .

Find the product: 1 5 × 1 5 × 1 2

Given, 1 5 × 1 5 × 1 2 We know that, a b × c d = a × c b × d Thus, 1 5 × 1 5 × 1 2 = 1 × 1 × 1 5 × 5 × 2 = 1 50 Hence, the required answer is 1 50 .

Find the product: 5 6 × 2 5

Given, 5 6 × 2 5 We know that, a b × c d = a × c b × d Thus, 5 6 × 2 5 = 5 × 2 6 × 5 = 10 1 30 3 = 1 3 Hence, the required answer is 1 3 .

Find the product: 4 5 × 6

Given, 4 5 × 6 We know that, a b × c d = a × c b × d Thus, 4 5 × 6 = 4 × 6 5 = 24 5 Hence, the required answer is 24 5 .

Find the product: 1 7 × 7 1

Given, 1 7 × 7 1 We know that, a b × c d = a × c b × d Thus, 1 7 × 7 1 = 1 × 7 7 × 1 = 7 7 = 1 Hence, the required answer is 1 .
