Question

If 5 choc ices cost 330p how much do 9 cost?

Answer 1

`5\ chock\ ices\ cost\ 330p\\ 9\ chock\ ices\ cost\ x\\\\\ Ratio:\\ 5-330\\ 9-x\\\\Cross\ multiplication\\\\\ 5x=330*9\\ 5x=2970\ \ \ | divide\ by\ 5\\ x=594\\\\ 9\ will\ cost\ 594p.`

Answer 2

use unitary method

for 5 it costs 330p

so for 1 choc it will cost 330/5

to get 9,

(330/5) =66

66 multiplied by 9 =594

therefore 9 will cost 594p
