Kris explains his method for simplifying a fraction Look for a common multiple of the numerator and the denominator

Divide the numerator and denominator by that common multiple

Check there are no more common multiples between the numerator and the denominator

What mistake has Kris made in his explanation of his method?

I dont think kris made a mistake
Explanation: lets try solving a fraction using kris’s method. Fraction:120/50
common multiple for both numbers:10
we divide 120 by 10 and 50 by 10= 12/5. We cant find and common multiples so thats the final answer.(using kris’s method)
if u try using a calculator u can see that the answer is 12/5 or 2.4. This means that kris’s method is not wrong
