Convert both fractions into top heavy fractions:
2 4/6 becomes 16/6
2 x 6 + 4 over 6
1 3/7 becomes 10/7
1 x 7 + 3 over 7
Next use KCF - Keep the first fraction the same, Change the sign to ´x’ and Flip the second fraction:
16/6 x 7/10
Finally multiply the numerators and denominators
16 x 7 = 112
6 x 10 = 60
112/60
Simplify:
112/60 = 56/30 = 28/15
