Answer:
3/10
Step-by-step 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)
