Jazmine is painting picture frames. She uses 1 tube of red paint and 2 tubes of yellow paint for every 5 frames. How many tubes of paint will she use for 20 picture frames?
She will use 12 tubes of paint for 20 frames. I got this by (below)
5 frames =3 tubes; so to get to 20 frames you do 5x4=20, which means you multiply 4x3=12 (if you need further explanation then let me know but hope this helps)
