2,25 = 9/4

Hiệu số phần bằng nhau là:

9 - 4 = 5 (phần)

Số bé là:

2,25 : 5 x 4 = 1,8

Đs...

2,25=9,4

số bé là

2,25 : 5 x 4 = 1,8

đ/s = 1,8

Câu hỏi 8:

Đổi: 2,25 = \(\frac{9}{4}\)

Số lớn là:

2,25 : ( 9 - 4 ) x 9 = 4,05

=> Số bé là:

4,05 - 2,25 = 1,8 

đ/s : 1,8

Câu hỏi 9:

Số tiền vốn là:

7 520 000 : ( 100 - 6 ) x 100 = 8 000 000 (đồng)

=> Số tiền bị lỗ là:

8 000 000 - 7 520 000 = 480 000 (đồng)

đ/s: 480 000 đồng

câu 8 :số bé là 1,8

câu 9 : số tiền bị lỗ là 450000 đồng

câu 8: 1,8

câu 9:480000
