About Smirnov: I am a pre-algebra student. I am in the Pre-algebra class in Ms. Blankenhorn's Honors math group in the 5th grade taking the 6th grade couse at Centennial Campus Middle School in raleigh, NC.
THE PROBLEM:
2%2F5-1%2F5=?
For this, where bothe denominators are the same, just subtract along the top.
2%2F5-1%2F5=1%2F5
THE PROBLEM:
2%2F3-1%2F6=?
To do this, you have to convert them to the same denominator:
2%2F3+=+4%2F6
4%2F6-1%2F6+=+3%2F6.
SIMPLIFY IF YOU CAN!
3%2F6+=+1%2F2
SOME PRACTICE:
2%2F5-2%2F10
3%2F9-5%2F9
326%2F125-13%2F50
21%2F3-11%2F8
