Question

How do you do this in simplest form

Answer 1

3/10

Explanation:

The LCD of these two denominators 10 and 4 is 20; 20 is the smallest integer divisible by both 10 and 4.

Rewriting the problem, we get:

16 10 6

---- - ----- = ------ = 3/10

20 20 20

Note that we could write 2/4 as 1/2 or as 5/10. If we write 5/10, then we have:

8/10 - 5/10 = 3/10 (same answer as before)
