In the 4 × 4 square grid as shown in the figure, ∠ 1 + ∠ 2 + ∠ 3 + ∠ 4 + ∠ 5 + ∠ 6 + ∠ 7 = ()
A. 330°B. 315°C. 310°D. 320°
It can be seen from the figure that: ① the congruence of the triangle where the residual angles of ∠ 4 = 12 × 90 ° = 45 °, ② ∠ 1 + 7 = 90 ° is the same as ∠ 2 + 6 = 90 °, and ∠ 3 + 5 = 90 °
62.5% of a is equal to 75% of B. what percentage of a is B
A * 62.5% = b * 75%
B * 75% = a * 62.5%
B = a * 62.5% * 100 / 75
B = a * 5 / 8 * 4 / 3
B = a * 5 / 6
B is five sixths of A
B is a: 62.5% △ 75% = 5 / 6
Fill 1,2,3,4,6,9,12,18,36 into the nine squares so that the product of the multiplication of the three numbers of horizontal, vertical and diagonal is 216
From left to right
First line: 2, 36, 3
The second line: 4, 6, 9
The third line: 12, 1, 18
In fact, there is a fixed method. The nine palaces can be solved quickly with small skills. If it is 16 palaces or even higher, you have to use multivariate functions. This will not be expanded. After all, the 16 palaces are very complicated
7 / 4-8 / 7-7 / 12 is a fraction

24 decimeters is a fraction of 5 meters
5m = 50m
24÷50
=24×1\50
=12\25
A: 24 decimeters is 12 / 25 of 5 meters
I hope my answer can help you,
12 out of 25~
As shown in the figure, ∠ AOB is an angle placed in the square grid, then the value of cos ∠ AOB is______ .
Suppose that the side length of a square is 12, then Ao = 5, Bo = 5, ab = 2. In △ AOB, according to the cosine theorem, AB2 = AO2 + bo2-2ao · Bo · cos ∠ AOB, ∧ 2 = 5 + 5-2 × 5 × cos ∠ AOB, ∧ cos ∠ AOB = 0.8, so the answer is 0.8
