Explanation

Explanation

Let the two numbers be $x$ and $y$, where $x > y$.

We are given:

$$x+y=40\text{(1)}$$$$x - y = 4 quad text{(2)}$$

Adding equations (1) and (2):

2x=44⟹x=22

Subtracting equation (2) from (1)

$$2y = 36 implies y = 18$$

The numbers are 22 and 18.
The ratio of the numbers is:

x​/y=22​/18

=11/9​

Waking - 1/3 hours = 20 min

Motorbike ride = 1/2 hours = 30 min

Total journey = 20 + 30 = 50 min

Portion of Bike ride = 30/50 = 0.6

Explanation

Let x = 0.125125125...

Multiply x by 1000:

1000x = 125.125125...

Subtract x from 1000x:

999x = 125

Divide by 999:

x = 125/999

Explanation

(1+1/x) (1+1/x+1) (1+1/x+2) (1 + 1/x + 3)

Simplify each term:

(x+1)/x * (x+2)/x * (x+3)/x * (x+4)/x

Multiply the numerators and denominators:

(x+1)(x+2)(x+3)(x+4) / x^4

Expand the numerator:

x^4 + 10x^3 + 35x^2 + 50x + 24

Divide by x^4:

1 + 10/x + 35/x^2 + 50/x^3 + 24/x^4

Now, simplify the expression:

Combine like terms:

x + 4/x

Explanation

If 4 is removed, the sum of the remaining numbers is 0 + 2 + 5 + 9 = 16.

The average remains the same, 16/4 = 4.
