Since she bought 4 bags of 50 beads and 3 bags of 200 beads you only need to use two operations: multiply and add.
4 x 50 is 200
3 x 200 is 600
600 + 200 = 800
Mariah purchase 800 beads in total.
The ratio given is 4:5 so you do 5divided by 20 which is 4 and multiply 4 and 4 and get 16 so your ratio is 16:20
1/2 of the beads will be blue, and 1/2 of them would be red Hope this helped!
