Math journal Dec 8 2011


Peter
100 ÷ 8 = 12.5
12.5 x 5 = 62.50
Peter spent $62.50 on a holiday present and saved $38.50

Raman
100 ÷ 3 =  33.33
33.3 x 2 = 66.66
Raman spent $66.66 and saved $33.3.

Patricia
6 x 10 = 60
4 x 10 = 40
40 + 60 = 100
Patricia spent $60 and saved $40. Since 6 + 4 = 10, and 10 x 10 = 100, which is the total for everyone, I multiplied both numbers by 10 to get the actual numbers.

Fiza
100 ÷ 5 = 20
20 x 4 = 80
Fiza spent $80 and saved $20.

Patricia saved the most money. She had $40 left over from buying a holiday present.
