Put the ten numbers 1,2,3,4,5,6,7,8,9,10 in the figure below, so that the sum of each four is equal to 24

It's better to tell the calculation process!

1 3 2
5 8 9 6
10 4 7
24*3-(1+10)*10/2=17
So the sum of the middle two is 17, which is 8 and 9
The rest is fine

Fill in the blanks from 1 to 12 so that the sum of the horizontal and vertical numbers equals 26
 

The sum of three numbers is twelve, four, five, two, three, six, one, eight, seven

Suppose the following filling method: a B C D E F G H I, then a + B + C + D + e + F + G + H + I > 1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 = 36  2 (a + B + C + D + e + F + G + H + I) > 72, and the sum of the three is equal to 12, then a + B + C = D + e + F = G + H + I = a + D + G = B + e + H = C + F + I = 12, then 2 (a + B + C + D + e + F + G + H + I) = 72

(7 / 12-1 / 8) / 24 * 2 / 5=

(7 / 12-1 / 8) / 24 * 2 / 5
=11/24÷24×2/5
=11/576×2/5
=11/1440

The following fractions are arranged in descending order: 1 / 2, 5 / 6 and 3 / 4, 3 / 4, 5 / 12 and 2 / 5

1/2=60/120
5/6=100/120
3/8=45/120
3/4=90/120
5/12=50/120
2/5=48/120
Now, can you line up

Put the following scores in descending order: 25 out of 96, 1 out of 3, 7 out of 24, 5 out of 6, 13 out of 48, 11 out of 12

25 out of 96, 13 out of 48, 7 out of 24, 1 out of 3, 5 out of 6, 11 out of 12

5 out of 6, 36 out of 31, 12 out of 7, 18 out of 11 rank the scores from small to large

7 out of 12 is less than 11 out of 18 is less than 5 out of 6 is less than 31 out of 36

Arrange the following numbers from small to large, 0.85, 5 / 6, 7 / 8, 0.88, 25 / 24

5/6

25 of 96, 1 of 3, 7 of 24, 6 of 5, 48 of 13, 11 of 12

25/96
1/3=32/96
7/24=28/96
5/6=80/96
13/48=26/96
11/12=88/96
Because 25 / 96
