Answer 2

Step-by-step explanation:

(i) 3/7 × 4/5

= (3 × 4)/(7 × 5)

= 12/35

(ii) 7/3 × 5/2

= (7 × 5)/(3 × 2)

= 35/6

(iii) 5 × 3/7

= 5/1 × 3/7

= (5 × 3)/(1 × 7)

= 15/7

(iv) 5/12 × 9

= 5/12 × 9/1

= (5 × 9)/(12 × 1)

= (5 × 3)/(4 × 1)

= 15/4

Sometimes for indicating multiplication of two fractions, we use the word ‘of ‘as follows:

(i) 1/2 of 8

= 1/2 × 8

= 1/2 × 8/1

= (1 × 8)/(2 × 1)

= 8/2

= 4

(ii) 1/5 of 20

= 1/5 × 20

= 1/5 × 20/1

= 20/5

= 4

(iii) 2/5 of 25

= 2/5 × 25

= 2/5 × 25/1

= (2 × 25)/(5 × 1)

= 50/5

= 10

(iv) 2/3 of 5/7

= 2/3 × 5/7

= (2 ×5)/(3 × 7)

= 10/21.
