Let’s do this by examples.

 

2/3 × 4

= (2 × 4)/3

= 8/3

 

9 / 8 × 2

= (9 × 2)/8

= 9/4

 

2/3 × 5/4

= (2 × 5)/(3 × 5)

= 10/12

 

4 × 3 2 / 7

= 4 × (3+2/7)

= 4 × ((3 × 7 + 2)/7)

= 4 × ((21 + 2)/7)

= 4 × 23/7

= (23 × 4)/7

= 92/7

7/2 × 4 3/5

= 7/2 × (4+3/5)

= 7/2 × ((4 × 5 + 3)/5)

= 7/2 × ((20 + 3)/5)

= 7/2 × 23/5

= (7 × 23)/(2 × 5)

= 161/10
