16 giờ trước (15:37)

2,55 x 10 + (3 + 1)

= 25,5 + 4

= 29,5

16 giờ trước (15:39)
Kết quả của phép tính là 29,5.Dưới đây là các bước thực hiện chi tiết:
  • Bước 1: Tính trong ngoặc trước
    \(3 + 1 = 4\)
  • Bước 2: Thực hiện phép nhân
    \(2,55 \times 10 = 25,5\)
  • Bước 3: Thực hiện phép cộng cuối cùng
    \(25,5 + 4 = 29,5\)

Bài 1: Chuyển các phân số và hỗn số thành số thập phân

11/1000 = 0,011

73/100 = 0,73

9/10 = 0,9

1 91/100 = 1,91

7 7/4 = 7 + 7/4 = 7 + 1,75 = 8,75

9 23/1000 = 9,023

Bài 2: Tính bằng cách thuận tiện

653 × 56 + 653 × 44

= 653 × (56 + 44)

= 653 × 100

= 65300

55/17 × 26/110 − 55/17 × 9/110

= 55/17 × (26/110 − 9/110)

= 55/17 × 17/110

= 55/110

= 1/2

Bài 3:

Đổi 950 kg = 0,95 tấn

Xe thứ nhất chở:

13/2 = 6,5 (tấn)

Xe thứ hai chở:

6,5 − 0,95 = 5,55 (tấn)

Cả hai xe chở:

6,5 + 5,55 = 12,05 (tấn)

Đáp số: 12,05 tấn cà phê

11/1000=0,011

73/100=0,73

9/10=0,9

1 91/100 = 191/100=1,91

7 7/4= 35/4= 8,75

9 23/1000= 9023/1000= 9,023

653x56+653x44= 653 x ( 56+44) = 653 x100 = 65300

Đôi khi, người mà bạn nhớ nhung lại chính là người mà bạn buộc phải buông tay. Tôi mỉm cười như thể chẳng có chuyện gì xảy ra, nhưng trái tim tôi vẫn khắc ghi tất cả. Có lẽ chúng ta được định sẵn để gặp gỡ, nhưng lại không có duyên để ở bên nhau mãi mãi.
