Question 1016227
If the denominator of 5/8 is increased by a number and the numerator is doubled, the result is 1.
 Find the number
:
let n = the number
{{{((2*5))/((n+8))}}} = 1 
multiply both sides by n+8
10 = 1(n+8)
10 - 8 = n
2 = n
:
If we add 2 to the denominator and double the numerator, we have 10/10
