a) since she made 72 bracelets on the 2nd day, on the first day she made 5/6 x 72 = 60 bracelets on the first day. since she made 1/6 of the total bracelets on the first day, the total number of bracelets she made is 6x60= 360 bracelets
b) since the total number of bracelets is 360, express the number of bracelets made on the second day over the total number of bracelets made
72/360 x 100% = 20%
b) since the total number of bracelets is 360, express the number of bracelets made on the second day over the total number of bracelets made
