Question

1/3-1/9= 10/21-1/3= 14/15-3/5= 17/18-1/9= 4/9-13/45= 1/3-7/30=

Answer 1

1/3-1/9=3/9-1/9=2/9

10/21-1/3=10/21-7/21=3/21=1/7

14/15-3/5=14/15-9/15=5/15=1/3

17/18-1/9=34/36-4/36=28/36=7/9

4/9-13/45=20/45-13/45=7/45

1/3-7/30=10/30-7/30=3/30=1/10

Answer 2

Let's solve each of these expressions step by step:

1. 1/3 - 1/9: To subtract fractions, they must have a common denominator. The common denominator here is 9. 1/3 - 1/9 = (3/9) - (1/9) = 2/9

2. 10/21 - 1/3: To subtract fractions, they must have a common denominator. The common denominator here is 3. 10/21 - 1/3 = 10/21 - (7/21) = 3/21 = 1/7

3. 14/15 - 3/5: To subtract fractions, they must have a common denominator. The common denominator here is 15. 14/15 - 3/5 = 14/15 - (9/15) = 5/15 = 1/3

4. 17/18 - 1/9: To subtract fractions, they must have a common denominator. The common denominator here is 18. 17/18 - 1/9 = 17/18 - (2/18) = 15/18 = 5/6

5. 4/9 - 13/45: To subtract fractions, they must have a common denominator. The common denominator here is 45. 4/9 - 13/45 = 20/45 - 13/45 = (20 - 13)/45 = 7/45

6. 1/3 - 7/30: To subtract fractions, they must have a common denominator. The common denominator here is 30. 1/3 - 7/30 = 10/30 - 7/30 = (10 - 7)/30 = 3/30 = 1/10

So the simplified results are:

1. 1/3 - 1/9 = 2/9
2. 10/21 - 1/3 = 1/7
3. 14/15 - 3/5 = 1/3
4. 17/18 - 1/9 = 5/6
5. 4/9 - 13/45 = 7/45
6. 1/3 - 7/30 = 1/10
