Question

If you wanted to find the difference of 6/25 minus 4/5 what common denominator would you choose and why?

Answer 1

When you find the least common denominator, you should first check if one is a multiple of the other: 2 is a multiple of 4 (2*2); 5 is a multiple of 25 (5*5).
In this case, since 5 is a multiple of 25, you would multiple (4/5) with (5/5), which would give you (20/25).
