Its max is 780
2/3 + 1/6 = 5/6
650/5=130
650+130=780
2 times 4/3= 8/3 8/3-6/3=2/3 therefore Clyde needs 2/3 cup more flour.
58 stamps is the number she gets each week. So if she went for one week, 58*1=58. 58*2=116 and so on. Because we don't know the exact number of weeks, we say 58w or 58*w because you multiply however many number of weeks she collects.
