Mr. Li divided 26 story books and 31 comic books to a group of students, and found that there were 2 more story books and 3 more comic books. How many students were there in this group at most

In this way, there are 26 storybooks, and two more, that is to say, there are 24;
Comic book 31, after 3, that is to say, 28
The largest number divisible by 24 and 28 is 4, so there are at most 4 students in this group
I hope it will be useful to you

Zhang Ming bought three story books and four comic books for 15.1 yuan. Each story book costs 2.9 yuan. How much is each comic book?
To solve the equation

Set X yuan per comic book
3*2.9+4X=15.1
8.7+4X=15.1
4X=15.1-8.7
4X=6.4
X=6.4/4
X=1.6
1.6 yuan per comic book

The formula 1.6.4 minus 3 times of a certain number is equal to 1.9. Find this number. The difference between 2.25 and 24 is less than 4 times of a number. Find this number

(6.4-1.9)/3=4.5-3=1.5
[(25-24)+1]/4=1/2

General division X / 4-2x, 1 / x ^ 2-4
How to divide? What is its simplest common denominator?

4-2x=-2(x-2)
x^2-4=(x+2)(x-2)
The simplest common denominator is 2 (x + 2) (X-2)
x/(4-2x)=-x/2(x-2)=-x(x+2)/2(x+2)(x-2)
1/(x^2-4)=2/2(x+2)(x-2)

How to calculate 15.7-4.83 + 4.3-5.17?

15.7+4.3-（4.83+5.17）=20-10=10

The limit of [(1 + MX) ^ n - (1 + NX) ^ m] / x ^ 2 when x tends to zero?

(1+m x)^n = 1 + n * (mx) + n(n-1)/2 * (mx)² + o(x³) (1+n x)^m = 1 + m * (nx) + m*(m-1)/2 * (nx)² + o(x³) => (1+m x)^n - (1+n x)^m = [n*(n-1) * m² - m*(m-1) * n² ]/2 * x&#...

Given that x = - 5 is the solution of the equation AX + B = 0, find the value of - 5A + B-2

Let x = - 5 equation AX + B = 0 be: - 5A + B = 0
-5a+b-2=-2

99.9x7.78 + 33.3x6.66

Original formula = 33.3x3x7.78 + 33.3x6.66
=33.3x(3x7.78+6.66)
=33.3x(23.34+6.66)
=33.3x30
=999

The nth number of 1,1 / 3,1 / 9,1 / 27 is

1,1/3,1/9,1/27
Every number is in the form of a power of 1 / 3, and the exponent starts at 0,
The nth number is (1 / 3) ^ (n-1)
0,1,3,7……
Add 1,
1,2,4,8
Every number is a power of 2, and the exponent starts at 0,
The original nth number is 2 ^ (n-1) - 1
