What fraction minus what fraction equals one in 1806?

What fraction minus what fraction equals one in 1806?

x-y=1
xy=1806
y=x+1
y^2+y=1806
y=43
x=42
So, 1 / 42-1 / 43 = 1 / 1806
You take "1806" (plus) and add one fraction (plus) to get another fraction (and),
Then you use the fraction (sum) you get to subtract and add the number (addend) that must be equal to "one in 1806"
1806=42×43
So 1 / 42-1 / 43 = 1 / 1806
1/602-1/903=1/1806;
Explain: first find the common divisor of 1806, 1806 / 2 = 903; 903 / 3 = 301
So, 3 / 1806-2 / 1806 = 1 / 1806
Thus, 1 / 602-1 / 903 = 1 / 1806;
Hey, hey
How many square meters is 2 cm by 2 cm?
2 * 2 = 4 square centimeter, is that equal to 0.04 square meter? Some people say it is equal to 4 square meters, if it is 4 square meters. Isn't 1 meter * 1 meter equal to 1 square meter? Some people say it is equal to 0.4 square meter. Which answer is correct?
It should be 0.0004 square meters, 1 square meter = 10000 square centimeters
1m = 100cm, that is to say, 1cm = 0.01M, 2cm = 0.02M, 0.02x0.02 = 0.0004m2.
One in 30 and one in 56 are equal to a fraction minus a fraction respectively
1/4-5/1
1/5-1/6
1/7-1/8
1 / 20 equals 1 / 10 minus 1 / 20,
1 / 30 equals 1 / 15 minus 1 / 30,
1 / 56 equals 1 / 28 minus 1 / 56.
One in 20 is one in four minus one in five
One in 30 is one in five minus one in six
One in 56 is one in seven minus one in eight
1 / 20 equals 1 / 10 minus 1 / 20,
1 / 30 equals 1 / 15 minus 1 / 30,
1 / 56 equals 1 / 28 minus 1 / 56.
The answer is not unique
1/20=1/4-1/5
1/30=1/5-1/6
1/56=1/7-1/8
1/4-1/5,1/5-1/6,1/7-1/8
1/20＝1/4×1/5＝1/4－1/5
1/30＝1/5×1/6＝1/5－1/6
1/56＝1/7－1/8

One quarter minus one fifth plus one a minus one twentieth equals one ninth
∵1/4-1/5+1/A-1/20=1/9
1/20+1/A-1/20=1/9
1/A=1/9
A=9
∴A=9
One quarter minus one fifth plus one a minus one twentieth is one ninth
1/4-1/5+1/A-1/20=1/9
1/20+1/A-1/20=1/9
1/A=1/9
A=9
1/4-1/5+1/a-1/20=1/9
5/20-4/20-1/20=1/9-1/a
1/9-1/a=0
A=9
1/A=1/9-1/4+1/5+1/20
1/A=1/9
A=9
1 / 4-1 / 5 + 1 / A-1 / 20 = 1 / 9 (general score)
1/20+1/A-1/20=1/9
1/A=1/9
A=9

How to add and subtract from 1-9 to 20
12-3+4+5-6+7-8+9＝20
Excuse me, can you say your question is impossible.
1 2 3 4 5 6 7 8 9, there are 5 odd numbers, 4 even numbers, 4 even numbers in the middle, no matter how the addition and subtraction are even numbers. How to add and subtract five odd numbers is odd. Odd plus even is always odd. So it's impossible to get 20 by adding and subtracting.
thank you.!
How many days does 25920 hours equal to asking God for help

Find the general term formula
[let the sequence {an} satisfy: A1 = 2, A2 = 1 (an) ^ 2 - (an-1) ^ 2 / (an-1) ^ 2 = (an + 1) ^ 2 - (an) ^ 2 / (an + 1) ^ 2 (n > = 2) find the general term formula an]
*: base number in brackets!
[an²-a(n-1)²]/a(n-1)²=[a(n+1)²-an²]/a(n+1)²
a(n+1)²a(n-1)²-an²a(n-1)²=a(n+1)²an²-a(n+1)²a(n-1)²
2a(n+1)²a(n-1)²=an²[a(n+1)²+a(n-1)²]
2/an²=1/a(n-1)²+1/a(n+1)²
1/an²-1/a(n-1)²=1/a(n+1)²-1/an²
1/a1²=1/4 1/a2²=1
1/a2²-1/a1²=1-1/4=3/4
The sequence {1 / an & sup2;} is an arithmetic sequence with 1 / 4 as the first term and 3 / 4 as the tolerance
1/an²=1/a1²+(n-1)(3/4)=(3n-2)/4
an²=4/(3n-2)
an=2/√(3n-2)=2√(3n-2)/(3n-2)
The general formula of sequence {an} is an = 2 √ (3n-2) / (3n-2)
