Question

On this necklace the ratio of black beads to white beads is 1:4

How many more black beads do you need to
add to make the ratio of black to white 4:1 ?

Answer 1

16

Explanation:

This is because the ratio of black to white can be set up as 1/4, for every one black bead there is 4 white so what is 1/4x that equals 4? simple, x=16 because 16/4 equals to 4 so it would be 4 black beads to 1 white bead.
