The sum of three consecutive even numbers is 66. What is the continuous ratio of these three numbers? What is the ratio after simplification?

The sum of three consecutive even numbers is 66. What is the continuous ratio of these three numbers? What is the ratio after simplification?

Let the middle even number of three consecutive even numbers be n, then the first one is n-2, and the last one is n + 2:1
N-2 + N + N + 2 = 66, n = 22, so the three even numbers are 20, 22, 24
Serial ratio: 20:22:24
After simplification, it is 10:11:12

There are five consecutive even numbers. It is known that the third number is 18 more than 14 of the sum of the first number and the fifth number. The sum of these five even numbers is______ ．

Let the first even number be x, then the following four numbers are in order: x + 2, x + 4, x + 6, x + 8. From the meaning of the title, we can get x + 4 - (x + X + 8) × 14 = 18 & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; X + 4-12x-2 = 18 & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp

Seven continuous even numbers are known, in which the maximum number is three times of the minimum number. The seven numbers are solved by equations

The smallest of the seven consecutive even numbers is 2x and the largest is 6x
(6x-2x)/6=2
x=3
These seven numbers: 6, 8, 10, 12, 14, 16, 18
