make the bottom number (denominator) the same on both fractions.
The least common denominator of 5/6 and 3/5 is 30 (5*6)
multiply 5/6 by 5/5 and 3/5 by 6/6
and you get
25/30-18/30 = 7/30

5/6 - 3/5 = 5/6 * 5/5 - 3/5 * 6/6
= 25/30 - 18/30
= 7/30
Make the denominator the LCM (Lowest common multiple) of both denominators. Multiply each numerator & denominator with the same number. Then subtract both numerators.

♥5/6-3/5 All you need to do to this is make the
denominators the same.
30 is a factor of 6 and 5 so make the denominator 30
25/30-18/30 Remember to multiply top and bottom
Answer: 7/30

You have to make your denominators equal multiply by the lowest common multiple.
5/6 = 25/30
3/5 = 18/30
25-18 = 7
so 7/30 which cannot be reduced.

5/6 -3/5 = 7/30
Take common factor 6 x 5 = 30
[(5x 5) - (3x 6)] whole divided by 30 = 7/30
