Question

What is the answer to 8/? + 5/? = 7/?

Answer 1

Step-by-step explanation:

well, the first solution that comes to my mind is :

8/4 + 5/1 = 7/1

2 + 5 = 7

the reason : the only numerator I can "cut" into integer pieces is 8.

5 and 7 are prime numbers.

so, it tried to keep 5 and 7 whole, and then add a part of 8 to make this equation true. and that worked right away.
