The number of A is reduced by 10 times, equal to the number of B = the number of A 10= the number of B; Number A 10 Number B.
Why 10+1, because when the number B is 1, the number A = 10x the number B, which adds up to (10+1).
First find the number B, and is the sum of the two numbers A and B, the number A is 10 B numbers, plus the B number itself, a total of 11 B numbers.
Or the number A is 23 and the number B is.
-
If the number A is reduced by 10 times and is equal to the number B, then the number A is 10 times the number B, and the sum of the number A plus the number B is the addition of 11 numbers B, then the number B is:
The number A is:
-
The number A is 23, and the number B is! According to the question conditions, the total number is divided into 11 parts, and the number A accounts for 10 parts, and the number B accounts for 1 part, then each part, the natural number A is 23, and the number B is!
-
Suppose the number A is x, the number B is y, x+y=
x/10=y
So, x+x 10=, x=23, and the number A is 23
-
A + B =
A 10 = B.
A + A 10=
11 10 A =
A = 23

B turned out to be 20. B 25 (B 15) 9
8b 135 25
B 20 The Law of Addition:
When using the "truncation method" in addition or subtraction, add or subtract directly from the left high position (while paying attention to whether the next digit needs to be carried or misplaced) until you get the answer that the option requires precision. When using the "truncation method" in multiplication or division, in order to make the results as accurate as possible, it is necessary to pay attention to the direction of the interception approximation:
1. To expand (or shrink) one multiplier factor, it is necessary to shrink (or expand) another multiplier factor.
2. To expand (or shrink) the dividend, it is necessary to expand (or shrink) the divisor. If you are looking for the sum or difference of the two products (i.e., a*b+ -c*d).
3. If one side of the plus sign is enlarged (or reduced), the other side of the plus sign needs to be narrowed (or expanded).
4. Enlarge (or reduce) one side of the minus sign, then enlarge (or reduce) the other side of the minus sign.

Elementary school normalization question types.
Per serving = (25 + 15) (9-1) = 5
B = 15 + 5 = 20.

How to reason that the two numbers of A and B are equal:?
-
The number A is 10 times the number of B.
Therefore, the number B of Suibi is 1/10 of the number of A
Therefore, the number A is: the answer of the Qing tribe is 1) = 23

Solution: The number of A is x, and the number of B is y. According to the title, x+y=120.........Sparrow silver ......①
x+20=4(y-5)……
The balance of the alliance is obtained by x=88 and y=32
Answer: It turns out that the number A is 88 and the number B is 32
-
120+20-5) (1+4)=27
27x4=108
It turns out that A and B are 88 and 32 respectively. The Rampant Imperial Rush faction.
-
The number B is: (5 3) * 10 = 50 3
The number of A is: (50 3) * 2-3 = 91 3
The number of A is more than the number of B: 91 3-50 3=41 3 Shrinkage Sen ten times smaller? There is no such thing as a limb to disappear the world, and it can only be said that it has been reduced to the original 1 10).

Summary. A is 550 and B is 5500.
The sum of the two numbers of A and B is 6050If the number of B is reduced by 10 times, it is equal, and how much A and B are.
A is 550 and B is 5500.
A: 6050 (10+1) 550, B: 550 10 5500 steps. The number B is reduced by 10 times, indicating that the two are a total of 11 copies.
First, find the quantity of each serving A: 6050 (10+1) 550, Min buried B: 550 10 5500
The difference between the two numbers of A and B is 2106If A expands 10 times, it is equal, and what are the two numbers of A and B.
Thank you. A: 2106 (10-1) 234, B 2106+234 2340
A: 2106 (10-1) 234, B 2106 + 234 2340 A: 2106 (10-1) 234, B 2106 + 234 2340 A:
2106 (10-1) 234, B 2106+234 2340

In other words, A is 10 times that of B, 209 is 11 times the hail of B, B Lameng = 209 11 = 19, A = 209-19 = 190
-
(140+25-5)÷(1+3)=40
It turns out that B number 40 + 5 = 45
It turns out that the number of A is 140-45 = 95
-
A + B = 140
A + 25 = 3 (B - 5) that is: 3 B - A = 40
Add the two formulas: 4B = 140 + 40 = 180
So B = 45
A = 140 - B = 140 - 45 = 95
-
The solution assumes that the number A is x and the number B is y, and according to the known conditions, x+y=140 and x+25=3(y-5) can be solved by combining the two equations, x=95 and y=45
Answer: The number A is 95, and the number B is 45
It is known that A is 920, which is 20 less than B, then B is 940, so the sum of the two is 920 + 940 1860
If the number A is two-fifths of the number B, then the number B is the number of A (five-two). >>>More
Solution: Let the smaller number be x, then the other is x+1 >>>More
Let the two numbers be a and b
then ab=9(a+b), i.e., ab-9a-9b=0, i.e.: (a-9)(b-9)=81 (Do you understand this step?) The 81 factoring factor is: >>>More
