Add the digits together and if 3 will divide evenly into the answer, it is divisible by 3
For instance:
6 + 9 = 15
15 /3 = 5
3 divides into 15 evenly so 69 is divisible by 3
10......................:)
The answer is zero because the line is completely horizontal
Let's look at the two denominators:
7= 7
4= 4
LCM(7,4)= 4*7= 28
5/7+ 1/4
= (5*4)/ (7*4)+ (1*7)/ (4*7)
= 20/28+ 7/28 (common denominator is 28)
= 27/28
The final answer is 27/28~
