Question

1/4=? /12=4/?=?/20=7/?=?/66​

Answer 1

1/4 = 3/12 = 4/16 = 5/20 = 7/28 = (16,5)/66 = 0,25

?/66 может ?/60, тогда 15/60 = 0,25

Answer 2

To solve the equations, we need to find the missing values denoted by question marks (?).

1. 1/4 = ?/12

To find the missing value, we can cross-multiply: 1 * 12 = 4 * ? 12 = 4 * ? ? = 12 / 4 ? = 3

So, the missing value is 3.

2. 4/? = ?/20

To find the missing value, we can cross-multiply: 4 * ? = ? * 20 4? = 20? ? = 20 / 4 ? = 5

So, the missing value is 5.

3. 7/? = ?/66

To find the missing value, we can cross-multiply: 7 * ? = ? * 66 7? = 66? ? = 66 / 7 ? = 9.42857... (rounded to 5 decimal places)

So, the missing value is approximately 9.42857 (rounded to 5 decimal places).

Please note that the last missing value is not an integer, but a decimal number rounded to five decimal places.
