Answer:

yan para hindi kana magtanong :(

Step-by-step explanation:

1. Multiply the numerators of the fractions (the top numbers).

2. Multiply the denominators of the fractions (the bottom numbers).

3. Simplify the fraction if needed to the lowest terms.

For example:

(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
