1-12 numbers, put them in the 4x4 square, and the four horizontal squares above are all 7, so that the sum of horizontal and vertical plus cross and oblique is equal to 28

1-12 numbers, put them in the 4x4 square, and the four horizontal squares above are all 7, so that the sum of horizontal and vertical plus cross and oblique is equal to 28

This is impossible, because according to the summation formula of arithmetic sequence: 1 + 2 +... + 11 + 12 = 78
But the sum of horizontal and vertical plus cross and oblique is equal to 28
Only look at the horizontal row, so there are four rows, each row is 28, the sum of all the numbers is 112, but actually only 28 + 78 = 106, so please check the question

Add eight numbers 1-8 and three numbers together to form a box with eight squares, so that the sum of three numbers on each side of the box is equal to fifteen

8 1 6
4 2
3 5 7

4.8.12.16.20.24.28.32.36 fill in 9 boxes so that the sum of the three numbers in horizontal, vertical and oblique lines is equal to 60?

From 1 to 9, the sum of the three numbers is equal to 15
4 9 2
3 5 7
8 1 6
From 4 to 36, they are four times as many as 1 to 9
16 36 8
12 20 28
32 4 24

75 = 1 / 4 () = 9: () = ()%

0.75 = 3 out of 4 = 9: (12) = (75)%
Do not understand can ask, help please adopt, thank you!

What's 8 = 9 = 0.75 = 4 plus 12 = 20?
also
How many parts of 24 = 5:8 = how many parts of 20 = 25 divided by what?
Add the number to the number. Thank you

6 △ 8 = 9 of 12 = 0.75 = 4 + 12 of 12 = 15 of 20
15 of 24 = 5:8 = 20 of 32 = 25 △ 40

0.75 = fraction 3 = fraction 12 = fraction 36 = fraction 45?

75 = 3 / 4 = 9 / 12 = 27 / 36 = 45 / 60
If you don't understand this question, you can ask,

(): 12 = 0.75 = 6: () = 36 ()

(9): 12 = 0.75 = 6: (8) = 27 out of 36
solution
:0.75=3/4
= 3×3/4×3
=9/12
=3×2/4×2
=3×9/4×9

(5 1 / 2-2.75) / [(2 / 7 + 2 1 / 2) * [5 4 / 11-0.8 + 2 7 / 11]
answer

(11/2-11/4)/((2/7+5/2)*(59/11-4/5+29/11))=(11/4)/(39/14*36/5)=385/2808

4 / 7 of 0.75 is equal to?

（3/4）*(7/4)=21/16

What is 3 / 4 / 6 + 0.75 × 2?

3 / 4 △ 1 / 6 + 0.75 × 2
=3/4 ×6+3/4×2
=3/4 ×(6+2)
=3/4 ×8
=6
