To make 7/11 equal to 3/4, we need to add the same number to both the numerator and denominator of 7/11. Let's call this number "x". Then, we have:
(7 + x)/(11 + x) = 3/4
To solve for "x", we can cross-multiply:
4(7 + x) = 3(11 + x)
Expanding both sides, we get:
28 + 4x = 33 + 3x
Subtracting 3x from both sides, we get:
x = 5
Therefore, we need to add 5 to both the numerator and denominator of 7/11 to make it equal to 3/4. This gives us:
(7 + 5)/(11 + 5) = 12/16
Simplifying the fraction, we get:
3/4
So, 7/11 + 5/16 = 3/4.
