For a fraction, the numerator is 10 less than the denominator, and it is equal to one third. What is the fraction?

For a fraction, the numerator is 10 less than the denominator, and it is equal to one third. What is the fraction?

Let the numerator be x and the denominator be x + 10. From the meaning of the question, we can get: & nbsp; XX + 10 = 13 & nbsp; & nbsp; & nbsp; & nbsp; 3x = x + 10 & nbsp; & nbsp; & nbsp; 3x-x = x-x + 10 & nbsp; & nbsp; & nbsp; & nbsp; 2x = 10 & nbsp; & nbsp; 2x △ 2 = 10 △ 2 & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; X = 5, so

What is a fraction whose numerator is 10 less than its denominator, which is equal to three fifths

Let this number be 3K / 5K, and K be an integer
So 3K + 10 = 5K
So k = 5
The score is 15 / 25

For a fraction, the numerator is 10 more than the denominator, and its fractional value is equal to five-thirds

Denominator = 10 (5 / 3-1) = 15
Molecule = 10 + 15 = 25
Score = 25 / 15
Do not understand can ask, help please adopt, thank you!

For a fraction, the numerator is 10 less than the denominator, and it is equal to three fifths. What is the fraction?
The formula is not

Denominator = 10 ÷ (5-3) × 5 = 25
Score = 15 / 25

How much is x equal to the power X of 5 multiplied by the power X of 25 = 625

5^x*25^x=625
5^x*5^2x=625
5^(x+2x)=5^4
5^3x=5^4
3x=4
x=4/3

Calculate the second power of (- 2), the second power of 2, the third power of (- 2), and the third power of 2. In connection with the power of this kind of specific number, do you think that when a < 0, the following expressions are true
Calculate the second power of (- 2), the second power of 2, the third power of (- 2), and the third power of 2. In connection with the power of such specific numbers, do you think the following formulas hold when a < 0?
1. The square of a > 0.2. The square of a = - A
3. The square of a = (- a) the square of 4. The third power of a = (- a) the third power

All four are established

If the absolute value of a = 8 and the absolute value of B = 4, find the value of a + B

A = 8 or - 8
B = 4 or - 4
A + B = 12 or 4 or - 4 or - 12

If one-fifth of M is 3, one-fifth of n2005 is 7, and m and N are natural numbers, then the number at the end of Mn is

The mantissa of M is 3, the mantissa of n is 7. According to the meaning of the title, the mantissa of M = 3 ^ 2005, n = 7 ^ 20053 is in the order of 3, 9, 7 and 1. (3 ^ 1 = 3, 3 ^ 2 = 9, 3 ^ 3 = 27, 3 ^ 4 = 81, 3 ^ 5 = 243,.) 2005 △ 4 = 501 So the mantissa of 3 ^ 2004 is 1,3 ^

Among the natural numbers greater than 2013, how many of them have the same quotient and remainder after being divided by 56?

A:
Let x > 2013
Let the quotient be y and the remainder be y

Using a natural number a to remove 2010, the quotient is 46, and the remainder is R. a = R=

a=2010x46+r
r＜46
