Answer: 1747067797/2500000000
Step-by-step explanation:
Rewrite the decimal number as a fraction with 1 in the denominator
0.6988271188=0.6988271188/1
Multiply to remove 10 decimal places. Here, you multiply top and bottom by 10 to the 10 power = 10000000000
0.6988271188/1 * 10000000000/10000000000 * 6988271188/10000000000
For this case we must solve the following quadratic equation:

Where:

The solution is given by:

Substituting:

Thus, we have two roots:

Step-by-step explanation:
Given the details :
Kofi is older than kweku
kofi's age = (5x-4) years
kweku's age = (2x+1) years
a. write down an expression, interns of x,for how much old is Kofi than kweku
Equate the ages of Kofi and kweku
(5x - 4) = (2x + 1)
5x - 4 = 2x + 1
5x - 2x = 1 + 4
3x = 5
3x - 5
B.) if Kofi is tens years older than kweku, find the value of x and the ages of Kofi and kweku
Then,
(5x-4) = (2x + 1) + 10
5x - 4 = 2x + 1 + 10
5x - 2x = 1 + 10 + 4
3x = 15
x = 5
Kofi's age : 5x - 4
5(5) - 4 = 25 - 4 = 21 years
Kweku's age : (2x + 1)
2(5) + 1 = 10 + 1 = 11 years
