4/7 - 2/5 = 6/35.
To subtract (or add) fractions make both fractions equivalent fractions with the same denominator. The LCM (Lowest Common Multiple) of 7 and 5 is 35, so convert both the fractions to equivalent fractions out of 35:
4/7 = 20/35
2/5 = 14/35
The subtraction can now be done:
4/7 - 2/5 = 20/35 - 14/35 = 6/35

What is 7 over 8 - 1 over 4?
5 over 8 or 5/8. To add or subtract fractions you must reach the lowest common denominator, which in this case is 8. So we multiply both the top and bottom of 1/4 by to to get the bottom to equal 8. We end up with 2/8. Then we just subtract the top numbers 7-2=5. so we end up with 5/8.
What is 4 5 subtract 2 10 and simplify?
Oh, what a happy little math problem we have here! To simplify this, we first subtract 5 from 4 to get -1, and then subtract 10 from 2 to get -8. So, the simplified answer is -1 - 8, which equals -9. Just remember, there are no mistakes in math, only happy little accidents!
