Answer:

11/2

Step-by-step explanation:

2*x/6+4*5/12=6*7/12

2x/6+20/12=42/12

2x/6+20/12-42/12=0

2x/6-22/12=0

2x*2/6*2-22/12=0

4x-22/12=0

4x-22=0

4x=22

x=22/4

x=11/2

Given:

2x/6 + 4*5/12 = 6*7/12

To Find:

Find the missing numerator

Solution:

Here, we have

2x/6 + 4*5/12 = 6*7/12

2x/6 + 20/12 = 42/12

2x/6 + 20/12 - 42/12 = 0

2x/6 - 22/12 = 0

2x*2/6*2 - 22/12 = 0

4x - 22/12 = 0

4x - 22 = 0

4x = 22

x = 22/4

x = 11/2

So,

Numerator = 2x = 11

Hence, the missing numerator is 11.
