Answer:
1. 1/4
2. 0
3. 1/7
4. 5/14
5. 7/18
6. 1
7. 2/9
8. 5/6
Step-by-step explanation:
1. 4/8 - 2/8 = 2/8 = 1/4
2. 10/24 - 5/12 = find LCD 10/24 - 5(2)/12(2)= 10/24 - 10/24 now that denominators are similar we can subtract = 0
3. 8/28 - 12/28 = 4/28 reduced by 4 = 1/7
4. 40/56(reduced by 4) - 10/28(reduced by 2) = 10/14 - 5/14 = 5/14
5. 5/9 - 2/12(reduced by 2) = 5/9 - 1/6 = Find LCD 5(2)/9(2) - 1(3)/6(3)= 10/18 - 3/18= 7/18
6. 18/28 + 10/28 = 28/28 = 1
7. 16/18 - 12/18 = 4/18 reduced by 2 = 2/9
8. 15/27(reduce by 3) + 10/36(reduce by 2) = 5/9 + 5/18 = Find LCD 5(2)/9(2) + 5/18 = 10/18 + 5/18 = 15/18 reduced by 3 = 5/6
