Start by multiplying the amount of white beads by 3 (there are 3 times more red than white!)
1,875 * 3 = 5,625 red beads.
Well, to find the TOTAL number of beads (red AND white), add the red beads (5,625) and the white beads (1,875).
5,625 + 1,875 = 7,500
So the answer is 7,500 beads (:
Hope this helped!
