You can either subtract the whole number portions, then subtract the numerators, or you can convert the mixed numbers to improper fractions, subtract the numerators, and simplify. For example, 3 5/7 - 2 1/7 can be handled as 3 - 2 and 5/7 - 1/7, or as 26/7 - 15/7; either way, it's 1 4/7.
By converting them to equivalent fractions with a common denominator. 1/5 = 7/35 1/7 = 5/35 1/5 - 1/7 = 2/35
2 - 1/8 = 1 + 1 - 1/8 = 1 + (1-1/8) = 1 + 7/8 or 17/8
7 times 6 is 42. If you subtract two, you get 42-2= 40.
Subtract is to take away a certain portion of a number. For example, if you subtract 5 from 7 (7-5), you take off 5 parts of 7, and get 2 as your answer.
1. Subtract 25 2. Then subtract 6 3. Then subtract 12 4. Then subtract 2 5. Then subtract 10 6. Then subtract 15 7. Then subtract 7 8. Then add 3 X 1/2 9. Then add 8

6 and 1/2
7 1/4 - 5 1/8 Change to common denominator 7 2/8 - 5 1/8 Subtract the whole numbers, then subtract the numerators of the fractions, don't subtract the denominators, just leave them as they are, and combine the results. 7-5 = 2 2-1 = 1 Answer: 2 1/8
You turn the 1 into an improper fraction (7/7) that is equal to 1. 7/7 - 5/7 = 2/7
You can't.
1 whole and 7 over 12
8 1/6 - 2 5/6 = 5 1/3. Here's how I did it. Borrow a 1 from the 8 and change it to 6/6 & add to 1/6, so you have 7 and 7/6. Subtract 5/6 from 7/6 = 2/6, which equals 1/3. Subtract 2 from 7 = 5.
-1/2+7/10
9-7= -2
-1,-2,+2,-4,+4,-5,+5, +0. the sequence is subtract twice, add once, subtract again, add, then subtract, then add twice.
