It is usually easier to convert mixed numbers to improper fractions and then do the subtraction.
To add/subtract fractions, the denominators (bottom numbers) must be equal; so first convert the fractions into equivalent fractions with the same denominator. Then the numerators (top numbers) are added/subtracted and the resulting fraction simplified (converting any improper fractions to mixed numbers);
→ 3 5/6 - 2 7/15 = (3×6+5)/6 - (2×15+7)/15
= 23/6 - 37/15
= (23×5)/(6×5) - (37×2)/(15×2)
= 115/30 - 74/30
= (115 - 74)/30
= 41/30
= (1×30 + 11)/30
= 1 11/30
3 and 2/5 minus 1 and 1/3 = 2 and 1/15
2/3 − 1/5 = 7/15
Expressed as a proper fraction in its simplest form, 4/5 - 2/15 = 2/3 or two thirds.
3/5 − 4/15 = 1/3
Well, darling, 17 over 18 minus 2 over 3 is the same as 17 times 3 minus 2 times 18, all over 18 times 3. So, that gives you 51 minus 36 over 54, which simplifies to 15 over 54, or 5 over 18. Math doesn't have to be a drag, honey!
2/3 minus 12/15 is -2/15
2/5 minus 1/15 is 1/3
2/3
3/5 − 3/15 = 2/5
10/15 - 3/15 = 7/15
12/15 - 10/15 = 2/15
3 and 2/5 minus 1 and 1/3 = 2 and 1/15
2 over 15 3/5 x 3/3 = 9/15 11/15 - 9/15 = 2/15
2/3 is.
17/18
2/3 − 1/5 = 7/15
1/3 minus 2/5 is -1/15
