6/13 = 3/c how do i find the simple solution?

Then, 6 x c = 39;

c = 39÷6;

c = 6.5;

in the math equation 8 x 7 = 56, the 8 and the 7 are both factors of 56, since in this lesson we will use square tiles to figure out the factors of a whole find as many different arrays as you can, but follow one important rule: all the rows must have the i can make two rows of nine, so 2 and 9 are both factors of 18.
