Answer 2

Answer:

( i ) 3/5 = p/15

cross multiply :-

3×15 = p×5

45 = 5p

45/5 = p

9 = p

(ii) 20/45 = p/9

cross multiply :-

20×9 = 45×p

180 = 45p

180/45 = p

4 = p

( iii ) 28/56 = 4/p

cross multiply :-

28×p = 56×4

28p = 224

p = 8

(iv) 3/4 = 24/p

cross multiply:-

3×p = 4×24

3p = 96

p = 32
