mình giải cho nè

Ta có: Hai lần rưỡi bằng 5 : 2
Theo bài ra ta có sơ đồ:
Tuổi Tôm trước đây 3 năm: !-----!-----!
Tuổi Tôm sau 3 năm nữa:    !-----!-----!-----!-----!-----!
Hiệu số phần bằng nhau là: 5 - 2 = 3 (phần)
3 phần bằng nhau tương ứng với số năm là: 3 + 3 = 6 (năm)
Suy ra: 1 phần tương ứng với số năm là: 6 : 3 = 2 (năm)
Tuổi Tôm trước đây 3 năm là: 2 x 2 = 4 (tuổi)
Tuổi Tôm hiện tại là: 4 + 3 = 7 (tuổi)

 đổi :Hai lần rưỡi= 5 phần 2
Theo bài ra ta có sơ đồ:
Tuổi Tôm trước đây 3 năm: !-----!-----!
Tuổi Tôm sau 3 năm nữa:    !-----!-----!-----!-----!-----!
Hiệu số phần bằng nhau là: 5 - 2 = 3 (phần)
3 phần bằng nhau tương ứng với số năm là: 3 + 3 = 6 (năm)
Suy ra: 1 phần tương ứng với số năm là: 6 : 3 = 2 (năm)
Tuổi Tôm trước đây 3 năm là: 2 x 2 = 4 (tuổi)
Tuổi Tôm hiện tại là: 4 + 3 = 7 (tuổi)
