Answer:
1. 1
2. 1/12
3. 3 1/6
Step-by-step explanation:
Solution for #1. First, you have to get a common denominator. Here, that would be 6. In order to give 1/2 a denominator of 6, you will need to multiply the numerator and the denominator by 3. That will give you 3/6. Add that to the other 3/6 (3/6+3/6) which equals 6/6 which can be simplified to 1.
Solution for #2. This is just like #1. First, you have to get a common denominator. Here, that would be 12. In order to give 1/3 a denominator of 12, you will need to multiply the numerator and the denominator by 4. That will give you 4/12. Then, to give 1/4 a denominator of 12, you will need to multiply the numerator and the denominator by 3. That will give you 3/12. Then, subtract (4/12-3/12). You will get an answer of 1/12.
Solution for #3. This is slightly different from the others, I has two more steps. First, you need to changed the mixed fractions into improper fractions. You will get 17/3 and 5/2. Then, you have to get a common denominator. Here, that would be 6. In order to give 17/3 a denominator of 6, you will need to multiply the numerator and the denominator by 2. That will give you 34/6. Then, to give 5/2 a denominator of 6, you will need to multiply the numerator and the denominator by 3. That will give you 15/6. After that, subtract (34/6-15/6). You should get 19/6. Finally, divide 19/6 and you should get 3R1. So, the mixed fraction version of 19/6 is 3 1/6 (I did this by using the 3 from 3R1 as the whole number and I just put the remainder of 1 over 6 as the fractional part). You can multiply to check your answer.

Answer: Jamian bought 20 bagels and 15 donuts
Step-by-step explanation:
Using the equation below:
b + d = 35 ...... i
1.25b + 0.75d = 36.25 ....... ii
Multiply i by 1.25
Multiply ii by 1
1.25b + 1.25d = 43.75 ...... iii
1.25b + 0.75d = 36.25 ....... iv
Subtract iv from iii
0.50d = 7.50
d = 7.50 / 0.50
d = 15
Since b + d = 35
b = 35 - 15
b = 20

Answer:
You can only add like terms with like terms, so the terms that can be combined with 3a are the terms that end in an a.
So, the answers are:
4a and 14a
