x + x%2F2 + x%2F4 = 10.
:
To get rid of the denominators mult equation by 4, this means mult each term in the equation by 4:
4*x + 4*x%2F2 + 4*x%2F4 = 4*10
:
This gets rid of the denominator and leaves you with:
4x + 2x + x = 40
:
7x = 40
:
x = 40/7
:
:
Check solution:
40%2F7 + 40%2F14 + 40%2F28 =
:
160%2F28 + 80%2F28 + 40%2F28 = 280%2F28 = 10
