hello for question 21, you know that 21 is a multiple of 7. how do we make the remainer a multiple of 7? since 14 is a multiple of 7, we need to add a number that will make it 14.

question 22, we find out the number of necklaces x 5 (which is the number of white beads).

let me know if you need further explanation ok? :)
